Bayesian Networks A causal probabilistic network, or Bayesian network, is an directed acyclic graph (DAG) where nodes represent variables and links represent.

Probabilistic (Bayesian) representations of knowledge have had a major impact on AI –contrast with symbolic/logical knowledge bases –necessity to handle.

Introduction to Probability Theory
Bayes Rule The product rule gives us two ways to factor a joint probability: Therefore, Why is this useful? –Can get diagnostic probability P(Cavity |
