Bayesian network

A form of artificial intelligence—named for Bayes’ theorem—which calculates probability based on a group of related or influential signs. Once a Bayesian network AI is taught the symptoms and probable indicators of a particular disease, it can assess the probability of that disease based on the frequency or number of signs in a patient.

Adopting Bayesian network as the framework of knowledge representation and inferences, the Chinese authors explore new approaches to uncertain knowledge discovery and fusion by incorporating the massive, distributed, uncertain, and dynamically changing characteristics concerned in data analysis applications.
A Bayesian network is defined as a "probabilistic graphical model" representing the causal relationships among variables based on the Bayes theorem, which allows the inference of a future event based on prior evidence (Pearl and Russel 2003).
The first is mathematical model-based, such as multinomial logistic regression and bayesian network (BN).
Objective: We aimed to evaluate the effectiveness of placebo, oral opioid analgesic (OOA), intravenous opioid analgesic (IOA), non-opioid analgesic (NOA), topical anesthetic (TA) and locally injected anesthetic (LIA) for pain relief during hysterosalpingography (HSG) using a Bayesian network meta-analysis of data from randomized controlled trials.
To predict how perturbation of the transcriptional network disrupts biological pathways, I will integrate in my Bayesian network model existing data sets of neuronal morphology, structural brain imaging GWAS, and behavioural studies in model organisms.

This paper develops a Bayesian Network (BN) model to examine the relationships among operational risk (OR) events in the three lines of business with greater losses in the international banking sector.
ABSTRACT: This study presented an innovative Bayesian Network (BN) modelling and simulation for supplier selection problem of an actual electronic parts manufacturing firm of Pakistan.
The parameters of the Bayesian network (BN) are also used to the graph structure conditional probability distributions (CPD) at each node.
The innovative aspect in this study was the use of a Bayesian network, which is a new methodology in the field of psychology, even though it is widely employed in other fields (Puga, 2012; Puga, Garcia, Guillen, Segura, & de la Fuente Sanchez, 2010).
In this study, we propose a logical approach that maximizes the true sentiment class probabilities of the popular Bayesian Network for a more effective sentiment classification task using the individual word sentiment scores from SentiWordNet.
