Ex4pmEngine.Cognition.BayesianNetwork (ex4pm v26.9.9)

Discrete Bayesian Network inference engine supporting exact marginalization, conditional belief updates, and variable elimination over directed acyclic graphs.

Summary

Types

t()

Functions

infer(bn, query_var, evidence \\ %{})

Performs exact inference to compute the posterior distribution P(Query | Evidence). evidence is a map of {node_name => observed_value}.

new(nodes, cpts, metadata \\ %{})

Constructs a new Bayesian Network with nodes and conditional probability tables.
