Bayesian belief network

An inference technique which provides a framework for reasoning despite uncertainty, based on the theory of probability. In a Bayesian belief network, each fact/assertion in the knowledge base is represented by a node.

Learning models in the form of Bayesian belief networks are developed with the help of a heuristic algorithm using the Bayesian function of network structure to distribution matching as a scoring function, named K2 (Jensen, 2001).
Lastly, our use of Bayesian Belief Network modeling is novel, and to our knowledge, we are one of the first to use this highly dimensional and robust artificial intelligence machine learning tool, which allowed us to test our primary and secondary questions under different scenarios while taking into consideration the omnidirectional relationships of target variables and confounders in a joint network.
