Explanations from "The Book of Why" about Bayesian Networks
- before discussing Bayesian networks, Pearl discusses the history and significance, using examples to further explain the concepts, of Bayes' rule and inverse probability from pages 95 - 108
- Pearl then connected this concept to Bayesian networks by discussing belief propagation from pages 108 - 112
- references past sections: "Although Bayes didn't know it, his rule for inverse probability represents the simplest Bayesian network. We have seen this network in several guises now: Tea -> Scones, Disease -> Test, or, more generally, Hypothesis -> Evidence" (Pearl, 2018, p. 112)
- explains the junctions present in both Bayesian networks and causal diagrams, using examples, from pages 113-116
- from pages 117 - 122, Pearl discusses conditional probability tables in relation to Bayesian networks and also mentions inverse-probability (previously discussed starting pages 97-99)
- from pages 122 - 133, Pearl discusses Bayesian networks in various contexts
- for the rest of the chapter (pages 128 - 133), Pearl compares Bayesian networks and causal diagrams
