Rules
  • If condition1 and condition2 then Consequence
  • Inference engine, lists of rules (knowledge
    base), data (database), knowledge encapsulation,
    explanation, user
  • Rule chaning foreward, backward, combinations
  • Deduction, abduction, induction
  • Semantic networks, objects, frames, trees,
    ontologies

4
some concepts
  • Declarative-procedural programming
  • Search depth-first, breadth-first, beam-search,
    alfa-beta, A
  • Meta-
  • Progaming languages Prolog, Logo, Lisp ...
  • Logic closed world

Probabilistic-Bayesian
  • Optimal in theory, in future not
  • P(HE) P(H)xP(EH) / P(E)
  • P(H)xP(EH)
  • P(HE) --------------------------------------
  • P(H)xP(EH) P(H)xP(EH)
  • Likehood ratio, odds
  • O(H) P(H)/ P(H)

Naïve Baesian Classifier
  • P(A1v1A2v2Cc)
  • P(CA) P(Cc) x ---------------------------------
  • P(A1v1A2v2)
  • P(A1v1Cc)xP(A2v2Cc)
