Datamining against Healthcare Waste – \$1.6 Trillion

Revolutionary Hyperbolic Dirac Net (HDN) based Data Mining Technique in fretting out Rogue Claims – Dr. Barry Robson, Ingine, Inc.

DiracSmash, or just SMASH for short, is a Q-UEL application in the sense that it is compatible with QUEL. It extracts probabilistic knowledge from csv files and renders it in the form of Q-UEL tags. DiracSmash is a development of techniques developed in The BioIngine.com, DiracMiner, DiracBuilder and other Q-UEL applications to treat sporadic data efficiently, and is being progressively adapted to handle sporadic data such as payment claims data. Note that Q-UEL has a full set of tags enabling translation of codes for diseases, procedures, triggers, complications, management etc to allow conversion from the codes to more readable forms. The typical and main purpose of

DiracSMASH is two fold, exemplified by the following. use case.

i. “data mining” and construction of potentially huge inference nets to obtain e.g. the probability that a payment will normally be above a certain amount given the input data, when for example a particular patient has obtained a claim for that amount, and

ii. “pattern discovery”, e.g. to help explain this probability by discovering patterns that are associated with cases where this probability is above that amount.

For example, it may build an HDN inference network (analogous to a Bayes Net but not confined to an Directed Acyclic Graph) implying thousands or millions of conditional probabilities, though for special reason discussed below (sporadic data), there are in this payment example merely 85 odds ratios as positive predictive odds and 85 as the corresponding odds likelihood ratio (analogous to relative risk), two probabilities comprising each, i.e. just 85 x 2 x2 = 340 probabilities.

################ NET of 85 odds ratios.

################ NETforward (predictive odds) = 2.038 ######################

################ NETbackward (likelihood ratio) = 16.477 ####################

################ NETassoc (ratio of association constants) = 9.098 #########

FORWARD PROBABILTY P(‘CLM_PMT_AMT’:=’ge100′ | NET) = 0.110

Joint probability ratio forward = 2.03780243432802 should ideally agree with following.

Joint probability ratio backward = 2.03103720070852

Real part = 2.03441981751827 (existential, coherence, extent of agreement).

Imaginary part = 0.00338261680975416 (universal, incoherence, extent of disagreement).

It can seek to help explain this with many discovered patterns, such as

<Q-UEL-PATFACTORS-3 ‘HCPCS_CD_32′:=’97110’ Pfwd:=0.00000529 | if:=count:=36 | ‘CLM_PMT_AMT’:=’ge100′ ‘ICD9_DGNS_CD_1′:=’V5832’ Q-UELPATFACTORS-3>

<Q-UEL-PATFACTORS-7 ‘ICD9_DGNS_CD_1′:=’V5832’ ‘ICD9_DGNS_CD_5′:=’78079’ ‘ICD9_PRCDR_CD_4′:=’40390’ ‘HCPCS_CD_33′:=’94762’ ‘HCPCS_CD_35′:=’94761’ Pfwd:=0.00000029 | if:=count:=2 | ‘CLM_PMT_AMT’:=’ge100′ ‘ICD9_DGNS_CD_1′:=’V5832’ Q-UEL-PATFACTORS-7>

The principles are not confined to the above scenario, nor even to payment data at all. No questions may be asked at all, and mining can still be done. Conversely, there may also be an indefinitely large list of “cases” (“conditions”, “constraints”, “denominators”) such as as say age, blood pressure 140 etc, and the data mining will apply to these cases considered collectively, i.e. to cases that satisfy all. The questions asked may also be of a different nature, such as equal or not equal to a name or code (see below). For example, the DiracSmash process produced list of all those tags having the predictive risk over 0.1 for the along with other supporting evidences, but this level is adjustable, as is an optional minimum number of required observations, and a test on significant information content. Although as noted above SMASH can be run without any guidance it is almost always given a “hitlist” file. For example

‘CLM_PMT_AMT’:=>’100′

‘ICD9_DGNS_CD_1′:=’V5832’

# ‘ICD9_DGNS_CD_2′:=’V5861’

# ‘ICD9_DGNS_CD_5′:=’V5869’

means predict and calculate probability for payment amounts greater than \$100, considering only cases in which ‘ICD9_DGNS_CD_1′:=’V5832’. Convenient input is X:=value, X:=>value, X:=<value, but a full range of logical comparitors, eq, ne, gt,ge, lt, le is available. Optionally the primary condition, the second line on the list, may also use the range notation. The two entries starting ‘#’ are simply ignored, and use of these “comment out” feature familiar to programmers allows one to experiment with various conditions ad constraints. The first line is special and called the “target”. Questions asked by the first line can be greater than (gt), less than (lt), greater than or equal to (ge), less than or equal to (le), or equal to (eq) or note equal to (ne), for quantitative data, or equal to (eq, here meaning the same as) or not equal to (ne, here meaning different to) specified categorical data. The alternative and more usual input is to use the following, though it converted to the above notation internally and in reports.

‘CLM_PMT_AMT’:=>’100′ (ge, this value or higher as opposed to less than)

‘CLM_PMT_AMT’:=<‘100’ (le, this value or lower as opposed to equal to of higher)

‘CLM_PMT_AMT’:= ‘100’ (eq, this value or word as opposed to anything else.

Relevant Definitions

Hyperbolic Dirac Net (HDN) – A probabilistic inference-based statistical reasoning algorithm and technology described in some detail below. An HDN may be considered as related to the Bayes Net (BN, see below) but, the HDN does not have the severe and unrealistic graph-theoretic constraints that define the traditional BN, and naturally extends to a more inference using general probabilistic semantics and exploiting natural language processing. The HDN approach was developed employing the following.

Q-UEL – Quantum Universal Exchange Language (Q-UEL) is an algebraic notational language derived from the Dirac Notation, the mathematical machinery that defines quantum mechanics and a long and widely accepted standard in physics. Q-UEL was originally proposed as an interoperability language in response [8-13] to a Federal report of the President’s Council of Advisors on Science and Technology for a Universal Exchange Language (UEL) for healthcare in December 2010 [14]. Q-UEL has from the outset been applied to electronic health records and biomedical data. Its concept endures as a powerful architectural principle, managing the problem of the interchange and merging of medical data and knowledge from a variety of formats and ontologies.

Dirac Notation – The HDN and Q-UEL are both based on the long used standard in quantum mechanics (QM) called Dirac Notation [15]. “Notation” is generally understood to be an understatement as it is also a algebra for expressing uncertainty in observations and measurements. The notational and algebraic aspects can also map to use in the everyday world, interpreting it as a probabilistic inference algorithm with semantic applications.

The BioIngine.com™ Platform

The BioIngine.com™offers a comprehensive bio-statistical reasoning experience in the application of the data science that blends descriptive and inferential statistical studies. Progressing further it will also blend NLP and AI to create a holistic Cognitive Experience.

The BioIngine.com™; is a High Performance Cloud Computing Platformdelivering HealthCare Large-Data Analytics capability derived from an ensemble of bio-statistical computations. The automated bio-statistical reasoning is a combination of “deterministic” and “probabilistic” methods employed against both structured and unstructured large data sets leading into Cognitive Reasoning.

The figure below depicts the healthcare analytics challenge as the order complexity is scaled.

Given the challenge of analyzing against the large data sets both structured (EHR data) and unstructured data; the emerging Healthcare analytics are around below discussed methods E (multivariate regression) and F (multivariate probabilistic inference); Ingine is unique in the Hyperbolic Dirac Net proposition for probabilistic inference.

The basic premise in engineering The BioIngine.com™ is in acknowledging the fact that in solving knowledge extraction from the large data sets (both structured and unstructured), one is confronted by very large data sets riddled with high-dimensionality and uncertainty.

A)   Descriptive Statistics :- Insights around :- “what”

For large data sets, descriptive statistics are adequate to extract a “what” perspective. Descriptive statistics generally delivers statistical summary of the ecosystem and the probabilistic distribution.

Descriptive statistics : Raw data often takes the form of a massive list, array, or database of labels and numbers. To make sense of the data, we can calculate summary statistics like the mean, median, and interquartile range. We can also visualize the data using graphical devices like histograms, scatterplots, and the empirical cdf. These methods are useful for both communicating and exploring the data to gain insight into its structure, such as whether it might follow a familiar probability distribution.

i)   Univariate Problem :- “what”

Considering some simplicity in the variables relationships or is cumulative effects between the independent variables (causing) and the dependent variables (outcomes):-

Univariate regression (simple independent variables to dependent variables analysis)

ii)    Bivariate Problem :- “what”

Correlation Cluster – shows impact of set of variables or segment analysis.

https://en.wikipedia.org/wiki/Correlation_clustering

From above link :- In machine learningcorrelation clustering or cluster editing operates in a scenario where the relationships between the objects are known instead of the actual representations of the objects. For example, given a weighted graph G = (V,E), where the edge weight indicates whether two nodes are similar (positive edge weight) or different (negative edge weight), the task is to find a clustering that either maximizes agreements (sum of positive edge weights within a cluster plus the absolute value of the sum of negative edge weights between clusters) or minimizes disagreements (absolute value of the sum of negative edge weights within a cluster plus the sum of positive edge weights across clusters). Unlike other clustering algorithms this does not require choosing the number of clusters k in advance because the objective, to minimize the sum of weights of the cut edges, is independent of the number of clusters.

http://www.statisticssolutions.com/correlation-pearson-kendall-spearman/

From above link. :- Correlation is a bivariate analysis that measures the strengths of association between two variables. In statistics, the value of the correlation coefficient varies between +1 and -1. When the value of the correlation coefficient lies around ± 1, then it is said to be a perfect degree of association between the two variables. As the correlation coefficient value goes towards 0, the relationship between the two variables will be weaker. Usually, in statistics, we measure three types of correlations: Pearson correlation, Kendall rank correlation and Spearman correlation

iii)   Multivariate Analysis (Complexity increases) :- “what”

§ Multiple regression (considering multiple univariate to analyze the effect of the independent variables on the outcomes)

Multivariate regression – where multiple causes and multiple outcomes exists

iv)   Neural Net :- “what”

The above discussed challenges of analyzing multivariate pushes us into techniques such as Neural Net; which is the next level to Multivariate Regression Statistical Approach…. where multiple regression models are feeding into the next level of clusters, again an array of multiple regression models.The above Neural Net method still remains inadequate in depicting “how” probably the human mind is operates. In discerning the health ecosystem for diagnostic purposes, for which “how”, “why” and “when” interrogatives becomes imperative to arrive at accurate diagnosis and target outcomes effectively. Its learning is “smudged out”. A little more precisely put: it is hard to interrogate a Neural Net because it is far from easy to see what are the weights mixed up in different pooled contributions, or where they come from.

“We Enter Probabilistic Computations which is as such Combinatorial Explosion Problem”.

Hyperbolic Dirac Net (Inverse or Dual Bayesian technique)

All the above are still discussing the “what” aspect. When the complexity increases the notion of independent and dependent variables become non-deterministic, since it is difficult to establish given the interactions, potentially including cyclic paths of influence in a network of interactions, amongst the variables. A very simple example in just a simple case is that obesity causes diabetes, but the also converse is true, and we may also suspect that obesity causes type 2 diabetes cause obesity. In such situation what is best as “subject” and what is best as “object” becomes difficult to establish. Existing inference network methods typically assume that the world can be represented by a Directional Acyclic Graph, more like a tree, but the real world is more complex than that that: metabolism, neural pathways, road maps, subway maps, concept maps, are not unidirectional, and they are more interactive, with cyclic routes. Furthermore, discovering the “how” aspect becomes important in the diagnosis of the episodes and to establish correct pathways, while also extracting the severe cases (chronic cases which is a multivariate problem). Indeterminism also creates an ontology that can be probabilistic, not crisp.

Note: From Healthcare Analytics perspective most Accountable Care Organization (ACO) analytics addresses the above based on the PQRS clinical factors, which are all quantitative. Barely useful for advancing the ACO into solving performance driven or value driven outcomes most of which are qualitative.

Notes On Statistics :-

Generally one enters Inferential Statistics an inductive reasoning when there is no clear distinction between independent and dependent variables, furthermore this problem is accentuated by multivariate condition. As such the problem becomes irreducible. Please refer to below MIT course work to gain better understanding on statistics, different statistical methods, descriptive and inferential. Particularly pay attention to Bayesian Statistics. HDN Inferential Statistics being introduced in The BioIngine.com is an advancement to Bayesian Statistics

Introduction to Statistics Class 10, 18.05,

Spring 2014 Jeremy Orloff and Jonathan Bloom

a)   What is a Statistics?

We give a simple definition whose meaning is best elucidated by examples. Definition. A statistic is anything that can be computed from the collected data.

The mathematical study of the likelihood and probability of events occurring based on known information and inferred by taking a limited number of samples. Statistics plays an extremely important role in many aspects of economics and science, allowing educated guesses to be made with a minimum of expensive or difficult-to-obtain data. A joke told about statistics (or, more precisely, about statisticians), runs as follows. Two statisticians are out hunting when one of them sees a duck. The first takes aim and shoots, but the bullet goes sailing past six inches too high. The second statistician also takes aim and shoots, but this time the bullet goes sailing past six inches too low. The two statisticians then give one another high fives and exclaim, “Got him!” (This joke plays on the fact that the mean of -6 and 6 is 0, so “on average, ” the two shots hit the duck.) Approximately 73.8474% of extant statistical jokes are maintained by Ramseyer.

b)   Descriptive statistics

Raw data often takes the form of a massive list, array, or database of labels and numbers. To make sense of the data, we can calculate summary statistics like the mean, median, and interquartile range. We can also visualize the data using graphical devices like histograms, scatterplots, and the empirical cdf. These methods are useful for both communicating and exploring the data to gain insight into its structure, such as whether it might follow a familiar probability distribution.

c)    Inferential statistics

https://www.coursera.org/specializations/social-science

Are concerned with making inferences based on relations found in the sample, to relations in the population. Inferential statistics help us decide, for example, whether the differences between groups that we see in our data are strong enough to provide support for our hypothesis that group differences exist in general, in the entire population.

i)     Frequentist – 19th Century

Hypothesis Stable – Evaluating Data

https://en.wikipedia.org/wiki/Frequentist_inference

Frequentist inference is a type of statistical inference that draws conclusions from sample data by emphasizing the frequency or proportion of the data. An alternative name is frequentist statistics. This is the inference framework in which the well-established methodologies of statistical hypothesis testing and confidence intervals are based.

ii)   Bayesian Inference – 20th Century

Data Held Stable – Evaluating Hypothesis

In scientific experiments we start with a hypothesis and collect data to test the hypothesis. We will often let H represent the event ‘our hypothesis is true’ and let D be the collected data. In these words Bayes theorem says

The left-hand term is the probability our hypothesis is true given the data we collected. This is precisely what we’d like to know. When all the probabilities on the right are known exactly, we can compute the probability on the left exactly. This will be our focus next week. Unfortunately, in practice we rarely know the exact values of all the terms on the right. Statisticians have developed a number of ways to cope with this lack of knowledge and still make useful inferences. We will be exploring these methods for the rest of the course.

A. Conditional Probability

P (A|B) is the probability of event A occurring, given that event B occurs.

https://en.wikipedia.org/wiki/Conditional_probability

In probability theoryconditional probability is a measure of the probability of an event given that (by assumption, presumption, assertion or evidence) another event has occurred.[1] If the event of interest is A and the event B is known or assumed to have occurred, “the conditional probability of A given B“, or “the probability of A under the condition B“, is usually written as P(A|B), or sometimes PB(A). For example, the probability that any given person has a cough on any given day may be only 5%. But if we know or assume that the person has a cold, then they are much more likely to be coughing. The conditional probability of coughing given that you have a cold might be a much higher 75%.

The concept of conditional probability is one of the most fundamental and one of the most important concepts in probability theory.[2] But conditional probabilities can be quite slippery and require careful interpretation.[3] For example, there need not be a causal or temporal relationship between A and B.

B. Joint Probability

https://en.wikipedia.org/wiki/Joint_probability_distribution

P (A,B) The probability of two or more events occurring together.

In the study of probability, given at least two random variables XY, …, that are defined on a probability space, the joint probability distribution for XY, … is a probability distribution that gives the probability that each of XY, … falls in any particular range or discrete set of values specified for that variable. In the case of only two random variables, this is called a bivariate distribution, but the concept generalizes to any number of random variables, giving a multivariate distribution.

Bayesian Rules

P(A | B) = P(A,B) / P(B)

P(B | A) = P(B,A) / P(A)

P(B | A) = P(A,B) / P(A)

P(A | B) P(B) = P(A,B)

P(B | A) P(A) = P(A,B)

P(A | B) P(B) = P(A,B) = P(B | A) P(A)

P(A | B) = P(B | A) P(A) / P(B)

Barry Robson Srinidhi Boray

The differences between a BN and an HDN are as follows. A BN is essentially an estimate of a complicated joint or conditional probability, complicated because it considers many factors, states, events, measurements etc., that by analogy with XML tags and hence Q-UEL tags, we call attributes in the HDN context. In a BN, the complicated probability is seen as a probabilistic-algebraic expansion into many simpler conditional probabilities of general form P(x | y) = P(x, y)/P(y), simpler because each have fewer attributes. For example, one such may be of more specific form P(G | B, D, F, H), where B, D, F, G, H are attributes and the vertical bar ‘|’ is effectively a logical operator that has the sense of “conditional upon” or “if”, “derived from the sample of”, “is a set with members” or sometimes “is caused by”. Along with simple, self or prior probabilities such as P(D) all these probabilities multiply together, which implies use of logical AND between the statements they represent, to give the estimate. It is an estimate because the use of probabilities with fewer attributes assumes that attributes separated by being in different probabilities are statistically independent of each other. As previously described [2], one key difference in an HDN is that the individual probabilities are bidirectional, using a dual probability (P(x|y), P(y|x)), say (P(B, G | D, F, H), P(D, F, H|B, G)) which is a complex value, i.e., with an imaginary part [1, 2]. Another, the subject of the present report, is that for these probabilities to serve as semantic triples such as subject-verb-object as the Semantic Web requires, the vertical bar must be replaced by many other kinds of relationship. Yet another, which will be described in great deal elsewhere, is that there can be other kinds of operator between probabilities as statements than just logical AND. All these aspects, and the notation used including for the format of Q-UEL, have direct analogies in the Dirac notation and algebra [8] developed in the 1920s and 1930s for quantum mechanics (QM). It is a widely accepted standard, the capabilities of which are described in Refs. [9-12] that are also excellent introductions. The primary difference between QM and Q-UEL and HDN methodologies is that the complex value in the latter cases is purely h-complex where is the hyperbolic imaginary number such that hh = +1. The significance of this is that it avoids a description of the world in terms of waves and so behaves in an essentially classical way.

Inductive (Inferential Statistics) Reasoning: – Hyperbolic Dirac Net Reference :- Notes on Synthesis of Forms by Christopher Alexander on Inductive Logic

The search for causal relations of this sort cannot be mechanically experimental or statistical; it requires interpretation: to practice it we must adopt the same kind of common sense that we have to make use of all the time in the inductive part of science. The data of scientific method never go further than to display regularities. We put structure into them only by inference and interpretation. In just the same way, the structural facts about a system of variables in an ensemble will come only from the thoughtful interpretation of observations.

We shall say that two variables interact if and only if the designer can find some reason (or conceptual model), which makes sense to him and tells him why they should do so.

But, in speaking of logic, we do not need to be concerned with processes of inference at all. While it is true that a great deal of what is generally understood to be logic is concerned with deduction, logic, in the widest sense, refers to something far more general. It is concerned with the form of abstract structures, and is involved the moment we make pictures of reality and then seek to manipulate these pictures so that we may look further into the reality itself. It is the business of logic to invent purely artificial structures of elements and relations.

Christopher Alexander: – Sometimes one of these structures is close enough to a real situation to be allowed to represent it. And then, because the logic is so tightly drawn, we gain insight into the reality, which was previously withheld from us.

What is the relative risk of needing to take BP medication if you are diabetic as opposed to not diabetic?

Note: – To conduct HDN Inference, bear in mind that getting all the combinations of factors by data mining is “ combinatorial explosion ” problem, which lies behind the difficulty of Big Data as high dimensional data.

It applies in any kind of data mining, though it is most clearly apparent when mining structured data, a kind of spreadsheet with many columns, each of which are our different dimensions. In considering combinations of demographic and clinical factors, say A, B, C, D, E.., we ideally have to count the number of combinations (A), (A,B) (A, C) …(B, C, E)…and so on. Though sometimes assumptions can be made, you cannot always deduce a combination with many factors from those with fewer, nor vice versa. In the case of the number N of factors A,B,C,D,E,… etc. the answer is that there are 2N-1 possible combinations. So data with 100 columns as factors would imply about

1,000,000,000,000,000,000,000,000,000,000

combinations, each of which we want to observe several times and so count them, to obtain probabilities. To find what we need without knowing what exactly it is in advance, distinguishes unsupervised data mining from statistics in which traditionally we test a hunch, a hypothesis. But worse still, in our spreadsheet the A, B, C, D, E are really to be seen as column headings with say about n possible different values in the columns below them, and so roughly we are speaking of potentially needing to count not just, say, males and females but each of nN different kinds of patient or thing. This results in truly astronomic number of different things, each to observe many time. If merely n=10, then nN is

10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,00,000,000

There is a further implied difficulty, which in a strange way lifts much the above challenge from the shoulders of researchers and of their computers. In most cases of the above, must of the things we are counting contain many of the factors A,B,C,D, E..etc. Such concurrences of so many things is typically rare, so many of the things we would like to count will never be seen at all, and most of the rest will just be seen 1, 2, or 3 times. Indeed, any reasonably rich patient record with lots of data will probably be unique on this planet. However, most approaches are unable to make proper use of that sparse data, since it seems that it would need to be weighted and taken into account in the balance of evidence according to the information it contains, and it is not evident how. The zeta approach tells us how to do that. In short, the real curse of high dimensionality is in practice not that our computers lack sufficient memory to hold all the different probabilities, but that this is also true for the universe: even in principle we do not have all the data to work to determine probabilities by counting with even if we could count and use them. Note that probabilities of things that are never observed are, in the usual interpretation of zeta theory and of Q-UEL, assumed to have probability 1. In a purely multiplicative inference net, multiplying by probability 1 will have no effect. Information I = –log(P) for P = 1 means that information I = 0. Most statements of knowledge are, as philosopher Karl Popper argued, assertions awaiting refutation.

Nonetheless the general approach in the fields of semantics, knowledge representation, and reasoning from it is to gather all the knowledge that can be got into a kind of vast and ever growing encyclopedia.

In The BioIngine.com™ the native data sets have been transformed into Semantic Lake or Knowledge Representation Store (KRS) based on Q-UEL Notational Language such that they are now amenable to HDN based Inferences. Where possible, probabilities are assigned, if not, the default probabilities are again 1.

The BioIngine.com – Deep Learning Comprehensive Statistical Framework – Descriptive to Probabilistic Inference

Given the challenge of analyzing against the large data sets both structured (EHR data) and unstructured data; the emerging Healthcare analytics are around below discussed methods d (multivariate regression), e (neural-net) and f (multivariate probabilistic inference); Ingine is unique in the Hyperbolic Dirac Net proposition for probabilistic inference.

The basic premise in engineering The BioIngine.com™ is in acknowledging the fact that in solving knowledge extraction from the large data sets (both structured and unstructured), one is confronted by very large data sets riddled with high-dimensionality and uncertainty.

Generally in solving insights from the large data sets the order in complexity is scaled as follows.

a)   Insights around :- “what”

For large data sets, descriptive statistics are adequate to extract a “what” perspective. Descriptive statistics generally delivers statistical summary of the ecosystem and the probabilistic distribution.

Descriptive statistics : Raw data often takes the form of a massive list, array, or database of labels and numbers. To make sense of the data, we can calculate summary statistics like the mean, median, and interquartile range. We can also visualize the data using graphical devices like histograms, scatterplots, and the empirical cdf. These methods are useful for both communicating and exploring the data to gain insight into its structure, such as whether it might follow a familiar probability distribution.

b)   Univariate Problem :- “what”

Considering some simplicity in the variables relationships or is cumulative effects between the independent variables (causing) and the dependent variables (outcomes):-

i) Univariate regression (simple independent variables to dependent variables analysis)

c)    Bivariate Problem :- “what”

Correlation Cluster – shows impact of set of variables or segment analysis.

d)   Multivariate Analysis (Complexity increases) :- “what”

§ Multiple regression (considering multiple univariate to analyze the effect of the independent variables on the outcomes)

§ Multivariate regression – where multiple causes and multiple outcomes exists

e)   Neural Net :- “what”

The above discussed challenges of analyzing multivariate pushes us into techniques such as Neural Net; which is the next level to Multivariate Regression Statistical Approach…. where multiple regression models are feeding into the next level of clusters, again an array of multiple regression models.

The above Neural Net method still remains inadequate in depicting “how” probably the human mind is operates. In discerning the health ecosystem for diagnostic purposes, for which “how”, “why” and “when” interrogatives becomes imperative to arrive at accurate diagnosis and target outcomes effectively. Its learning is “smudged out”. A little more precisely put: it is hard to interrogate a Neural Net because it is far from easy to see what are the weights mixed up in different pooled contributions, or where they come from.

“So we enter Probabilistic Computations which is as such Combinatorial Explosion Problem”.

f)    Hyperbolic Dirac Net (Inverse or Dual Bayesian technique): – “how”, “why”, “when” in addition to “what”.

All the above are still discussing the “what” aspect. When the complexity increases the notion of independent and dependent variables become non-deterministic, since it is difficult to establish given the interactions, potentially including cyclic paths of influence in a network of interactions, amongst the variables. A very simple example in just a simple case is that obesity causes diabetes, but the also converse is true, and we may also suspect that obesity causes type 2 diabetes cause obesity. In such situation what is best as “subject” and what is best as “object” becomes difficult to establish. Existing inference network methods typically assume that the world can be represented by a Directional Acyclic Graph, more like a tree, but the real world is more complex than that that: metabolism, neural pathways, road maps, subway maps, concept maps, are not unidirectional, and they are more interactive, with cyclic routes. Furthermore, discovering the “how” aspect becomes important in the diagnosis of the episodes and to establish correct pathways, while also extracting the severe cases (chronic cases which is a multivariate problem). Indeterminism also creates an ontology that can be probabilistic, not crisp.

Note: From Healthcare Analytics perspective most Accountable Care Organization (ACO) analytics addresses the above based on the PQRS clinical factors, which are all quantitative. Barely useful for advancing the ACO into solving performance driven or value driven outcomes most of which are qualitative.

To conduct HDN Inference, bear in mind that getting all the combinations of factors by data mining is “ combinatorial explosion ” problem, which lies behind the difficulty of Big Data as high dimensional data.

It applies in any kind of data mining, though it is most clearly apparent when mining structured data, a kind of spreadsheet with many columns, each of which are our different dimensions. In considering combinations of demographic and clinical factors, say A, B, C, D, E.., we ideally have to count the number of combinations (A), (A,B) (A, C) …(B, C, E)…and so on. Though sometimes assumptions can be made, you cannot always deduce a combination with many factors from those with fewer, nor vice versa. In the case of the number N of factors A,B,C,D,E,… etc. the answer is that there are 2N-1 possible combinations. So data with 100 columns as factors would imply about

1,000,000,000,000,000,000,000,000,000,000

combinations, each of which we want to observe several times and so count them, to obtain probabilities. To find what we need without knowing what exactly it is in advance, distinguishes unsupervised data mining from statistics in which traditionally we test a hunch, a hypothesis. But worse still, in our spreadsheet the A, B, C, D, E are really to be seen as column headings with say about n possible different values in the columns below them, and so roughly we are speaking of potentially needing to count not just, say, males and females but each of nN different kinds of patient or thing. This results in truly astronomic number of different things, each to observe many time. If merely n=10, then nN is

10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,00,000,000

There is a further implied difficulty, which in a strange way lifts much the above challenge from the shoulders of researchers and of their computers. In most cases of the above, must of the things we are counting contain many of the factors A,B,C,D, E..etc. Such concurrences of so many things is typically rare, so many of the things we would like to count will never be seen at all, and most of the rest will just be seen 1, 2, or 3 times. Indeed, any reasonably rich patient record with lots of data will probably be unique on this planet. However, most approaches are unable to make proper use of that sparse data, since it seems that it would need to be weighted and taken into account in the balance of evidence according to the information it contains, and it is not evident how. The zeta approach tells us how to do that. In short, the real curse of high dimensionality is in practice not that our computers lack sufficient memory to hold all the different probabilities, but that this is also true for the universe: even in principle we do not have all the data to work to determine probabilities by counting with even if we could count and use them. Note that probabilities of things that are never observed are, in the usual interpretation of zeta theory and of Q-UEL, assumed to have probability 1. In a purely multiplicative inference net, multiplying by probability 1 will have no effect. Information I = –log(P) for P = 1 means that information I = 0. Most statements of knowledge are, as philosopher Karl Popper argued, assertions awaiting refutation.

Nonetheless the general approach in the fields of semantics, knowledge representation, and reasoning from it is to gather all the knowledge that can be got into a kind of vast and ever growing encyclopedia.

In The BioIngine.com™ the native data sets have been transformed into Semantic Lake or Knowledge Representation Store (KRS) based on Q-UEL Notational Language such that they are now amenable to HDN based Inferences. Where possible, probabilities are assigned, if not, the default probabilities are again 1.

Formulating a researchable question: A critical step for facilitating good clinical research

MARPLE – Question Format Medical Exam / PICO Setting

A good way to use Marple/HDNsudent is to set it up like an exam then the student answers. Marple then answers with its choices, i.e. candidate answers ranked by probability proposing its own choice of answer as the most probable and explaining why it did that (by the knowledge elements successfully used). This can then be compared with the intended answer of the examiner of which, of course Marple’s probability assessment of it can be seen.

It is already the case that MARPLE is used to test exam questions and it is scary that questions that have been issued by a Medical Licensing Board can turn out to be assigned an incorrect or unreachable answer by the examiner. The reason on inspection is that the question was ambiguous and potentially misleading, even though that may have not been obvious, or simply out of date – progress in science changed the answer and it shows up fast on some new web page (Translational Research for Medicine in action!). Often it is wrong or misleading because there turns out to be a very strong alternative answer.

Formulating the Questions in PICO Format

The modern approach to formulation is the recommendation for medical best practice known as PICO.

• P is the patient, population or problem (Primarily, what is the disease/diagnosis Dx?)
• I is intervention or something happening that intervenes (What is the proposed therapy Rx (drug, surgery, or life style recommendation)
• C is some alternative to that intervention or something happening that can be compared (with what options (including no treatment)? May also include this in the context of different compared types of patient female, diabetic, elderly, or Hispanic etc.
• O is the outcome, i.e. a disease state or set of such that occurs, or fails to occur, or is ideally terminated by the intervention such that health is restored. (Possibly that often means the prognosis, but often prognosis implies a more complex scenario on a longer timescale further in the future).

Put briefly “For P does I as opposed to C have outcome O” is the PICO form.

The above kinds of probabilities are not necessarily the same as an essentially statistical analysis by structured data mining would deliver. All of these except C relate to associations, symptoms, Dx, Rx, outcome.  It is C that is difficult. Probably the best interpretation is replacing Rx in associations with no Rx and then various other Rx. If C means say in other kinds of patients, then it is a matter of associations including those.

A second step of quantification is usually required in which probabilities are obtained as measures of scope based on counting. Of particular interest here is the odds ratio

Two Primary Methods of Asking a Question in The BioIngine

1. Primarily Symbolic and Qualitative. (more unstructured data dependent) [Release 1]

HDN is behind the scenes but focuses mainly on contextual probabilities between statements. HDNstudent is used to address the issue as a multiple choice exam with indefinitely large numbers of candidate answers, in which the expert end-user can formulate PICO questions and candidate answers, or all these can be derived automatically or semi-automatically. Each initial question can be split into a P, I, C, and O question.

2. Primarily Calculative and Quantitative. (more structured – EHR data dependent) [Release 2]

Focus on intrinsic probabilities, the degree of truth associated with each statement by itself. DiracBuilder used after DiracMiner addresses EBM decision measures as special cases of HDN inference. Of particular interest is an entry

<O |  P, I > / <O   |  P, C>

which is the HDN likelihood or HDN relative risk of the outcome O given patient/population/problem P given I as opposed to C, usually seen as a “NOT I”, and

<NOT O  |  P, I> / <NOT O | P, C>

which is the HDN likelihood or HDN relative risk of NOT getting the outcome O given patient/population/problem P given I as opposed to C usually seen as a “NOT I”. Note though that you get a two for one, because we also have <P, I |  O>, the adjoint form, at the same time, because on the complex conjugate of the other. Note that the ODDS RATIO is the former likelihood ratio over the latter, and hence the HDN odds ratio as it would normally be entered in DiracBuilder is as follows:-

<O | P, I>

/<NOT O | P, C>

<NOT O | P, C>

/<NOT O | P, I>

• QUALITATIVE / SYMBOLIC

An 84-year-old man in a nursing home has increasing poorly localized lower abdominal pain recurring every 3-4 hours over the past 3 days. He has no nausea or vomiting; the last bowel movement was not recorded. Examination shows a soft abdomen with a palpable, slightly tender, lower left abdominal mass. Hematocrit is 28%. Leukocyte count is 10,000/mm3. Serum amylase activity is within normal limits. Test of the stool for occult blood is positive. What is the diagnosis?

•This is usually addressed by a declared list of multiple choice candidate answers, though the list can be indefinitely large. 30 is not unusual.

•The answers are all assigned probabilities, and the most probable is considered the answer, at least for testing purposes in a medical licensing exam context. These probabilities can make use of probabilities, but predominantly they are contextual probabilities, depending in the relationships between chains and networks of knowledge elements that link the question to each answer.

• QUANTITATIVE / CALCULATIVE:

Will my female patient age 50-59 taking diabetes medication and having a body mass index of 30-39 have very high cholesterol if the systolic BP is 130-139 mmHg and HDL is 50-59 mg/dL and non-HDL is 120-129 mg/dL?”.

•This forms a preliminary  Hyperbolic Dirac Net (inference net) from the query, which may be refined and to each statement intrinsic probabilities are assigned, e.g. automatically by data mining.

•This question could properly start “What is the probability that…” . The real answers of interest here are not qualitative statements, but the final probabilities.

•Note the “IF”. But POPPER extends this to relationships beyond IF associative or conditional ones, e.g. verbs of action.

Examples Quantitative / Calculative HDN Queries

In The Bioingine.com Release 1 – we are only dealing with Quantitative / Calculative type questions

Examples discussed in section A below are simple to play with to appreciate the HDN power for conducting inference. However, Problems B2 onwards requires some deeper understanding of the Bayesian and HDN analysis.

<‘Taking BP medication’:=’1’ |  ‘Taking diabetes medication’:= ‘1’>

/<‘Taking BP medication’:=’1’ | ‘Taking diabetes medication’:= ‘0’>

A.   Against Data Set 1.csv (2114 records with 33 variables created for Cardiovascular Risk Studies (Framingham Risk Factor)

B.   Against Data Set2.csv (nearing 700,000 records with 196 variables. Truly a large data set with high dimensionality (many columns of clinical and demographic factors), leading to a combinatorial explosion.

Note: in the examples below, you are forming questions or HDN queries such as

For African Caribbean patients 50-59 years old with a BMI of 50-59 what is the Relative Risk of needing to be on BP medication if there is a family history as opposed to no family history?

IMPORTANT: THE TWO-FOR-ONE EFFECT OF THE DUAL. Calculations report a dual value for any probabilistic value implied for the expression ented. In some cases you may be only interest in the first number in the dual, but the second number is always meaningful and frequently very useful. Notably, we say Relative Risk by itself for brevity, but in fact this is only the first number in the dual that is reported. In general, the form

<’A’:=’1’|’B’:=’1’>

/<’A’:=’1’|’B’:=’0’>

yields the following  dual probabilistic value…

(P(’A’:=’1’|’B’:=’1’)/ P(’A’:=’1’|’B’:=’0’),   ( P(’B’:=’1’|’A’:=’1’)/ P(’B’:=0’|’B’:=’1’),

where the first ratio is relative risk RR(P(’A’:=’1’|’B’:=’1’) and the second ratio is predictive odds RR(P(’A’:=’1’|’B’:=’1’).

a.   This inquiry seeking the risk of BP requires being translated into Q-UEL specification as shown below. [All the below Q-UEL queries in red can be copied and entered in the HDN query to get the HDN inference for the pertinent Data Sets.]

< ‘Taking BP medication’:=’1’ | ‘Family history of BP’:=’1 ‘ and ‘Ethnicity’:=‘African Caribbean’ and ‘age(years):=’50-59’ and BMI:= ’50-59’ >

/< ‘Taking BP medication’:=’1’ | ‘Family history of BP’:=’0’ and ‘Ethnicity’:=‘African Caribbean’ and ‘age(years):=’50-59’ and ‘BMI’:= ’50-59’ >

b.    The Q-UEL specified query enables Notational Algebra to work while making inference from the giant semantic lake or the knowledge repository store (KRS).

c.    Recall, KRS is the representation of the universe as a Hyperbolic Dirac Net. This was created by transformation process of the uploaded data set to activate the automated statistical studies.

d.    The query works against the KRS and extracts the inference in HDN format displaying an inverse Bayesian Result; which calculates both classical and zeta probabilities :- Pfwd, Pzfwd & Pbwd, Pzbwd

A1. Relative Risk – High BP Case

Example: – Study of BP = blood pressure (high) in the population data set considered.

This case is very similar, because high BP and diabetes are each comorbidities with high BMI and hence to some extent with each other. Consequently we just substitute diabetes by BP throughout.

Note: for the values enter discreet or continuous

(0) We can in fact test the strength of the above with the following RR, which in effect reads as “What is the relative risk of needing to take BP medication if you are diabetic as opposed to not diabetic?

<‘Taking BP medication’:=’1’ | ‘Taking diabetes medication’:= ‘1’>

/<‘Taking BP medication’:=’1’ | ‘Taking diabetes medication’:= ‘0’>

The following predictive odds PO make sense and are useful here:-

<‘Taking BP medication’:=’1’ | ‘BMI’:= ’50-59’ >

/<‘Taking BP medication’:=’0’ | ‘BMI’:= ’50-59’ >

and (separately entered)

<‘Taking diabetes medication’:=’1’ | ‘BMI’:= ’50-59’ >

/<‘Taking diabetes medication’:=’0’ | ‘BMI’:= ’50-59’ >

And the odds ratio OR would be a good measure here (as it works in both directions). Note Pfwd = Pbw theoretically for an odds ratio.

<‘Taking BP medication’:=’1’ | ‘Taking diabetes medication’:= ‘1’>

<‘Taking BP medication’:=’0’ | ‘Taking diabetes medication’:= ‘0’>

/<‘Taking BP medication’:=’1’ | ‘Taking diabetes medication’:= ‘0’>

The BioIngine.com™

Ingine; Inc™, The BioIngine.com™, DiracIngine™, MARPLE™ are all Ingine Inc © and Trademark Protected; also The BioIngine.com is Patent Pending IP belonging to Ingine; Inc™.

High Performance Cloud based Cognitive Computing Platform

The below figure depicts the healthcare analytics challenge as the order of complexity is scaled.

1. Introduction Beta Release 1.0

It is our pleasure to introduce startup venture Ingine; Inc that brings to market The BioIngine.com™Cognitive Computing Platform for the Healthcare market, delivering Medical Automated Reasoning Programming Language Environment (MARPLE) capability based on the mathematics borrowed from several disciplines and notably from late Prof Paul A M Dirac’s Quantum Mechanics.

The BioIngine.com™; is a High Performance Cloud Computing Platformdelivering HealthCare Large-Data Analytics capability derived from an ensemble of bio-statistical computations. The automated bio-statistical reasoning is a combination of “deterministic” and “probabilistic” methods employed against both structured and unstructured large data sets leading into Cognitive Reasoning.

The BioIngine.com™; delivers Medical Automated Reasoning based on a Medical Automated Programming Language Environment (MARPLE) capability, so better achieving 2nd order semantic interoperability1 in the Healthcare ecosystem. (Appendix Notes)

The BioIngine.com™ is a result of several years of efforts with Dr. Barry Robson; former Chief Scientific Officer, IBM Global Healthcare, Pharmaceutical and Life Science. His research has been in developing quantum math driven exchange and inference language achieving semantic interoperability, while also enabling Clinical Decision Support System, that is inherently Evidence Based Medicine (EBM). The solution, besides enabling EBM, also delivers knowledge graphs for Public Health surveys including those sought by epidemiologists. Based on Dr Robson’s experience in the biopharmaceutical industry and pioneering efforts in bioinformatics, this has the data mining driven potential to advance pathways planning from clinical to pharmacogenomics.

The BioIngine.com™; brings the machinery of Quantum Mechanics to Healthcare analytics; delivering a comprehensive data science experience that covers both Patient Health and Population Health (Epidemiology) analytics, driven by a range of bio-statistical methods from descriptive to inferential statistics, leading into evidence driven medical reasoning.

The BioIngine.com™; transforms the large clinical data sets generated by interoperability architectures, such as in Health Information Exchange (HIE) into “semantic lake” representing the Health ecosystem that is more amenable to bio-statistical reasoning and knowledge representation. This capability delivers evidence-based knowledge needed for Clinical Decision Support System, better achieving Clinical Efficacy by helping to reduce medical errors.

The BioIngine.com™; platform working against large clinical data sets or while residing within the large Patient Health Information Exchange (HIE) works in creating opportunity for Clinical Efficacy, while it also facilitates in the better achievement of “Efficiencies in the Healthcare Management” that Accountable Care Organization (ACO) seeks.

Our endeavors have resulted in the development of revolutionary Data Science to deliver Health Knowledge by Probabilistic Inference. The solution developed addresses critical areas in both scientific and technical, notably the healthcare interoperability challenges of delivering semantically relevant knowledge both at patient health (clinical) and public health level (Accountable Care Organization).

2. WhyThe BioIngine.com™?

The basic premise in engineering The BioIngine.com™ is in acknowledging the fact that in solving knowledge extraction from the large data sets (both structured and unstructured), one is confronted by very large data sets riddled by high-dimensionality and uncertainty.

Generally in solving insights from the large data sets the order in complexity is scaled as follows:-

A. Insights around :- “what”

For large data sets, descriptive statistics are adequate to extract a “what” perspective. Descriptive statistics generally delivers statistical summary of the ecosystem and the probabilistic distribution.

B. Univariate Problem :- “what”

Considering some simplicity in the variables relationships or is cumulative effects between the independent variables (causing) and the dependent variables (outcomes):-

a) Univariate regression (simple independent variables to dependent variables analysis)

b) Correlation Cluster – shows impact of set of variables or segment analysis.

https://en.wikipedia.org/wiki/Correlation_clustering

C. Multivariate Analysis (Complexity increases) :- “what”

a) Multiple regression (considering multiple univariate to analyze the effect of the independent variables on the outcomes)

b) Multivariate regression – where multiple causes and multiple outcomes exists

All the above are still discussing the “what” aspect. When the complexity increases the notion of independent and dependent variables become non-deterministic, since it is difficult to establish given the interactions, potentially including cyclic paths of influence in a network of interactions, amongst the variables. A very simple example in just a simple case is that obesity causes diabetes, but the also converse is true, and we may also suspect that obesity causes type 2 diabetes cause obesity… In such situation what is best as “subject” and what is best as “object” becomes difficult to establish. Existing inference network methods typically assume that the world can be represented by a Directional Acyclic Graph, more like a tree, but the real world is more complex than that that: metabolism, neural pathways, road maps, subway maps, concept maps, are not unidirectional, and they are more interactive, with cyclic routes. Furthermore, discovering the “how” aspect becomes important in the diagnosis of the episodes and to establish correct pathways, while also extracting the severe cases (chronic cases which is a multivariate problem). Indeterminism also creates an ontology that can be probabilistic, not crisp.

Most ACO analytics addresses the above based on the PQRS clinical factors, which are all quantitative. Barely useful for advancing the ACO into solving performance driven or value driven outcomes most of which are qualitative.

D. Neural Net :- “what”

https://www.wolfram.com/language/11/neural-networks/?product=mathematica

The above discussed challenges of analyzing multivariate pushes us into techniques such as Neural Net; which is the next level to Multivariate Regression Statistical Approach…. where multiple regression models are feeding into the next level of clusters, again an array of multiple regression models.

The Neural Net method still remains inadequate in exposing “how” probably the human mind is organized in discerning the health ecosystem for diagnostic purposes, for which “how”, “why”, “when” etc becomes imperative to arrive at accurate diagnosis and target outcomes efficiently. Its learning is “smudged out”. A little more precisely put: it is hard to interrogate a Neural Net because it is far from easy to see what are the weights mixed up in different pooled contributions, or where they come from.

“So we enter Probabilistic Computations which is as such Combinatorial Explosion Problem”.

E. Hyperbolic Dirac Net (Inverse or Dual Bayesian technique): – “how”, “why”, “when” in addition to “what”.

Note:- Beta Release 1.0 only addresses HDN transformation and inference query against the structured data sets and Features A, B and E. However, as a non-packaged solution C and D features can still be explored.

Release 2.0 will deliver full A.I driven reasoning capability MARPLE working against both structured and unstructured data sets. Furthermore, it will be designed to be customized for EBM driven “Point Of Care” and “Care Planning” productized user experience.

The BioIngine.com™offers a comprehensive bio-statistical reasoning experience in the application of the data science as discussed above that blends descriptive and inferential statistical studies.

The BioIngine.com™; is a High Performance Cloud Computing Platformdelivering HealthCare Large-Data Analytics capability derived from an ensemble of bio-statistical computations. The automated bio-statistical reasoning is a combination of “deterministic” and “probabilistic” methods employed against both structured and unstructured large data sets leading into Cognitive Reasoning.

Given the challenge of analyzing against the large data sets both structured (EHR data) and unstructured data; the emerging Healthcare analytics are around above discussed methods D and E; Ingine Inc is unique in the Hyperbolic Dirac Net proposition.

GENERATIVE SYSTEM :-

https://ingine.wordpress.com/2013/01/09/generative-transformation-system-is-the-method/

A Large Chaotic System driven by Human Social Structures has two contending ways.

a. Natural Selection – Adaptive – Darwinian – Natural Selection – Survival Of Fittest – Dominance

b. Self Regulation – Generative – Innovation – Diversity – Cambrian Explosion – Unique Peculiarities – Co Existence – Emergent

Accountable Care Organization (ACO) driven by Affordability Care Act transforms the present Healthcare System that is adaptive (competitive) into generative (collaborative / co-ordinated) to achieve inclusive success and partake in the savings achieved. This is a generative systemic response contrasting the functional and competitive response of an adaptive system.

Natural selection seems to have resulted in functional transformation, where adaptive is the mode; does not account for diversity.

Self Regulation – seems like is a systemic outcome due to integrative influence (ecosystem), responding to the system constraints. Accounts for rich diversity.

The observer learns generatively from the system constraints for the type of reflexive response required (Refer – Generative Grammar – Immune System – http://www.ncbi.nlm.nih.gov/pmc/articles/PMC554270/pdf/emboj00269-0006.pdf)

From the above observation, should the theory in self regulation seem more correct and that adheres to laws of nature, in which generative learning occurs. Then, the assertion is “method” is offered by the system itself. System’s ontology has an implicate knowledge of the processes required for transformation (David Bohm – Implicate Order)

For very large complex system,

System itself is the method – impetus is the “constraint”.

In the video below, the ability for the cells to creatively create the script is discussed which makes the case for self regulated and generative complex system in addition to complex adaptive system.

Further Notes on Q-UEL / HDN :-

1. That brings Quantum Mechanics (QM) machinery to Medical Science.
2. Is derived from Dirac Notation that helped in defining the framework for describing the QM. The resulting framework or language is Q-UEL and it delivers a mechanism for inferential statistics – “Hyperbolic Dirac Net”
3. Created from System Dynamics and Systems Thinking Perspective.
4. It is Systemic in approach; where System is itself the Method.
5. Engages probabilistic ontology and semantics.
6. Creates a mathematical framework to advance Inferential Statistics to study highly chaotic complex system.
7. Is an algorithmic approach that creates Semantic Architecture of the problem or phenomena under study.
8. The algorithmic approach is a blend of linguistics semantics, artificial intelligence and systems theory.
9. The algorithm creates the Semantic Architecture defined by Probabilistic Ontology :- representing the Ecosystem Knowledge distribution based on Graph Theory

To make a decision in any domain, first of all the knowledge compendium of the domain or the system knowledge is imperative.

System Riddled with Complexity is generally a Multivariate System, as such creating much uncertainty

A highly complex system being non-deterministic, requires probabilistic approaches to discern, study and model the system.

General Characteristics of Complex System Methods

• Descriptive statistics are employed to study “WHAT” aspects of the System
• Inferential Statistics are applied to study “HOW”, “WHEN”, “WHY” and “WHERE” probing both spatial and temporal aspects.
• In a highly complex system; the causality becomes indeterminable; meaning the correlation or relationships between the independent and dependent variables are not obviously established. Also, they seem to interchange the position. This creates dilemma between :- subject vs object, causes vs outcomes.
• Approaching a highly complex system, since the priori and posterior are not definable; inferential techniques where hypothesis are fixed before the beginning the study of the system become enviable technique.

Review of Inferential Techniques as the Complexity is Scaled

Step 1:- Simple System (turbulence level:-1)

Frequentist :- simplest classical or traditional statistics; employed treating data random with a steady state hypothesis – system is considered not uncertain (simple system). In Frequentist notions of statistics, probability is dealt as classical measures based only on the idea of counting and proportion. This technique is applied to probability to data, where the data sets are rather small.

Increase complexity: Larger data sets, multivariate, hypothesis model is not established, large variety of variables; each can combine (conditional and joint) in many different ways to produce the effect.

Step 2:- Complex System (turbulence level:-2)

Bayesian :- hypothesis is considered probabilistic, while data is held at steady state. In Bayesian notions of statistics, probability is of the hypothesis for a given sets of data that is fixed. That is, hypothesis is random and data is fixed. The knowledge extracted contains the more subjectivist notions of uncertainty, belief, reliability, or confidence often used in automated inference and decision support systems.

Additionally the hypothesis can be explored only in an acyclic fashion creating Directed Acyclic Graphs (DAG)

Increase the throttle on the complexity: Very large data sets, both structured and unstructured,  Hypothesis random, multiple Hypothesis possible, Anomalies can exist, There are hidden conditions, need arises to discover the “probabilistic ontology” as they represent the system and the behavior within.

Step 3: Highly Chaotic Complex System (turbulence level:-3)

Certainly DAG is now inadequate, since we need to check probabilities as correlations and also causations of the variables, and if they conform to a hypothesis producing pattern, meaning some ontology is discovered which describes the peculiar intrinsic behavior among a specific combinations of the variables to represent a hypothesis condition. And, there are many such possibilities within the system, hence  very chaotic and complex system.

Now the System itself seems probabilistic; regardless of the hypothesis and the data. This demands Multi-Lateral Cognitive approach

Telandic …. “Point – equilibrium – steady state – periodic (oscillatory) – quasiperiodic – Chaotic – and telandic (goal seeking behavior) are examples of behavior here placed in order of increasing complexity”

A Highly Complex System, demands a Dragon Slayer – Hyperbolic Dirac Net (HDN) driven Statistics (BI-directional Bayesian) for extracting the Knowledge from a Chaotic Uncertain System.

Algorithm based on Hyperbolic Dirac Net (HDN)

An HDN is a dualization procedure performed on a given inference net that consists of a pair of split-complex number factorizations of the joint probability and its dual (adjoint, reverse direction of conditionality). Hyperbolic Dirac Net is derived from Dirac Notational Algebra that forms the mechanism to define Quantum Mechanics.

A Hyperbolic Dirac Net (HDN) is a truly Bayesian model and a probabilistic general graph model that includes cause and effect as players of equal importance. It is taken from the mathematics of Nobel Laureate Paul A. M. Dirac that has become standard notation and algebra in physics for some 70 years.  It includes but goes beyond the Bayes Net that is seen as a special and (arguably) usually misleading case. In attune with nature, the HDN does not constrain interactions and may contain cyclic paths in the graphs representing the probabilistic relationships between all things (states, events, observations, measurements etc.).  In the larger picture, HDNs define a probabilistic semantics and so are not confined to conditional relationships, and they can evolve under logical, grammatical, definitional and other relationships. It is also, in its larger context, a model of the nature of natural language and human reasoning based on it that takes account of uncertainty.

Explanation: An HDN is an inference net, but it is also best explained by showing that it stands in sharp contrast to the current notion of an inference net that, for historical reasons, is today often taken as meaning the same thing as a  Bayes Net. “A Bayesian network, Bayes network, belief network, Bayes(ian) model or probabilistic directed acyclic graphical model is a probabilistic graphical model (a type of statistical model) that represents a set of random variables and their conditional dependencies via a directed acyclic graph (DAG). For example, a Bayesian network could represent the probabilistic relationships between diseases and symptoms. Given symptoms, the network can be used to compute the probabilities of the presence of various diseases.”  [https://en.wikipedia.org/ wiki/Bayesian_ network].  In practice, such nets have little to do with Bayes, nor Bayes’ rule, law, theorem or equation that  allows verification that probabilities used are consistent with each other and all other probabilities that can be derived from data. Most importantly, in reality, all things interact in the manner of a general graph, and a DAG is in general a poor model of reality since it consequently may miss key interactions.

DiracMiner

Is a machine learning based biostatistical algorithm that transforms Large Data Sets such as Millions of Patient Records  into Semantic Lake as defined by HDN driven computations that is a mix of Numbers theory (Riemann Zeta) and Information Theory (Dual Bayesian or HDN)

The HDN – Semantic Lake, represents the health-ecosystem as captured in Knowledge Representation Store (KRS) consisting of Billions of Tags (Q-UEL Tags).

DiracBuilder

Send an HDN query to KRS to seek HDN probabilistic inference / estimate. The Query for the inference contains the HDN that the user would like to have, and DiracBuilder helps get the best similar dual net by looking at what Billions of QUEL tags and joint probabilities are available.

High Performance Cloud Computing

The Bioingine.com Platform computes (probabilistic computations) against the billions of Q-UEL tags employing extended in-memory processing technique. The creation of the billions of Q-UEL tags and querying against them is combinatorial explosionproblem.

The Bioingine platform working against large clinical data sets or while residing within the large Patient Health Information Exchange (HIE) works in creating opportunity for Clinical Efficacy and also facilitates in the better achievement of “Efficiencies in the Healthcare Management” that ACO seeks.

EBM Diagnostic Risk Factors and Calculating Predictive Odds

Q-UEL tags of form

< A Pfwd:=x |  assoc:=y | B Pbwd:=z >

Say A = disease, B = cause,  drug,  or diagnostic prediction of disease, are designed to imply the following, knowing numbers x, y, and z.

P(A|B) = x

K(A; B) = P(A,B) / (P(A)P(B))   = y

P(BIA) = z

From which we can calculate the following….

P(A) = P(A|B)/K(A;B)

P(B) = P(B|A)/K(A;B)

P( NOT A) = 1 – P(A)

P(NOT B) = 1 – P(B)

P(A, B) = P(A|B)P(B) = P(B|A) P(A)

P(NOT A,  B)= P(B) – P(A B)

P(A, NOT B) = P(A) – P(A B)

P(NOT A, NOT B) = 1 – P(A, B) – P(NOT A, B) – P(A NOT B)

P(NOT A | B)  = 1  – P(A|B)

P(NOT B | A) = 1 –  P(B|A)

P(A | NOT B) =  P(A, NOT B)/P(NOT B)

P(B | NOT A) =  P(NOT A, B)/P(NOT A)

Positive Predictive Value P+ = P(A | B)

Negative Predictive value  P- = P(NOTA | NOT B)

Sensitivity = P(B | A)

Specificity = P(NOT B | NOT A)

Accuracy A =   P(A | B) + P(NOT A | NOT B)

Predictive odds PO = P(A | B) / P(NOT A | B)

Relative Risk RR = Positive likelihood ratio  LR+ =  P(A | B) / P(A | NOT B)

Negative  likelihood ratio  LR- =  P(NOT A | B) /  NOT A | NOT B)

Odds ratio OR = P(A, B)P(NOT A, NOT B)  /  (  P(NOT A,  B)P(A, NOT B) )

Absolute risk reduction ARR =  P(NOT A | B) – P(A | B) (where A is disease and B is drug etc).

Number  Needed to Treat NNT = +1 / ARR if ARR > 0 (giving positive result)

Number  Needed to Harm  NNH = -1 / ARR  if ARR > 0 (giving positive result)

Example:-

BP = blood pressure (high)

This case is very similar, because high BP and diabetes are each comorbidities with high BMI and hence to some extent with each other.  Consequently we just substitute diabetes by BP throughout.

(0) We can in f act test the strength of the above  with the following RR, which in effect reads as “What is the relative risk of needing to take BP medication if you are diabetic as opposed to not diabetic?

<‘Taking BP  medication’:=’1’  |  ‘Taking diabetes medication’:= ‘1’>

/<‘Taking BP  medication’:=’1’  | ‘Taking diabetes medication’:= ‘0’>

The following predictive odds  PO make sense and are useful here:-

<‘Taking BP  medication’:=’1’  |  ‘BMI’:= ’50-59’  >

/<‘Taking BP  medication’:=’0’  |  ‘BMI’:= ’50-59’  >

and (separately entered)

<‘Taking diabets medication’:=’1’  |  ‘BMI’:= ’50-59’  >

/<‘Taking diabetes  medication’:=’0’  |  ‘BMI’:= ’50-59’  >

And the odds ratio OR would be a good measure here (as it works in both directions). Note Pfwd = Pbw theoretically for an odds ratio.

<‘Taking BP  medication’:=’1’  | ‘Taking diabetes medication’:= ‘1’>

<‘Taking BP  medication’:=’0’  | ‘Taking diabetes medication’:= ‘0’>

/<‘Taking BP  medication’:=’1’  | ‘Taking diabetes medication’:= ‘0’>

/<‘Taking BP  medication’:=’0’  | ‘Taking diabetes medication’:= ‘1’>
