**BioIngine.com Platform**

Is High Performance Cloud Computing Platform delivering both probabilistic and deterministic computations; while combining HDN Inferential Statistics and Descriptive Statics.

The bio-statistical reasoning algorithm have been implemented in the Wolfram Language; which is a knowledge based programming unified symbolic language. As such symbolic language has a good synergy in implementing Dirac Notational Algebra.

The Bioingine.com; brings the Quantum Mechanics machinery to Healthcare analytics; delivering a comprehensive data science experience that covers both Patient Health and Public Health 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.

**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.

Our endeavors have resulted in the development of revolutionary Data Science to deliver Health Knowledge by Probabilistic Inference. The solution developed addresses critical areas 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).

**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’>
