Conditional Independence — The Backbone of Bayesian Networks

WebUnderstanding Bayesian networks in AI. A Bayesian network is a type of graphical model that uses probability to determine the occurrence of an event. It is also known as a belief network or a causal network. It consists of directed cyclic graphs (DCGs) and a table of conditional probabilities to find out the probability of an event happening. WebOct 5, 2024 · A. Conditional Independence in Bayesian Network (aka Graphical Models) A Bayesian network represents a joint distribution using a graph. Specifically, it is a directed acyclic graph in which each edge is a conditional dependency, and each node is a distinctive random variable.
