Bayesian Network

Bayesian networks do not necessarily imply a commitment to Bayesian statistics. Bayesian networks are a useful representation for hierarchical Bayesian models, which form the foundation of applied Bayesian statistics. It is a probabilistic graphical model, which is a type of statistical model that represents a set of random variables and their conditional dependencies via a directed acyclic graph (DAG).Bayesian network could represent the probabilistic relationships between diseases and symptoms.
