WHEN PROBABILISTIC REASONING IS "AI":

• BN architecture and prob estimates are heuristics
• a component of an AI system
  • sensor input as evidence (ie, is
• applied to machine induction
  • induce BN tables or architecture
  • Naive Bayes
• BN is KR -- fancy semantics
  • normal KR is symbolic/non-numeric
  • queries are inference, reasoning -- fancy semantics
• when applied to "AI" applications
  • expert system, e.g., genetics, diagnosis
  • when some probs in BN are adhoc, it is an expert system
  • speech recognition: HMM
  • simlution to control a stochastic agent, e.g., games
