Bayesian networks, also known as belief networks (Belief Network, BN), or directed acyclic graph models, are composed of a Directed acyclic graphical model (DAG) and a conditional probability distribution (ie know P(xi) |parent(xi)) Probability of occurrence, where parent(xi) is the direct parent to xi. It is an uncertainty processing model that simulates causality in human reasoning. Its network topology is a directed acyclic graph (DAG).
