Bayes)
Hypothesis, Enidence
Prior, Likehood, Posterior
P(H|E) = P(H) * P(E|H) / P(E)
Conditional independent 하다고 가정
->
= P(H) * P(E1 n E2|H) / P(E1 n E2)
= P(H) * P(E|H)* P(E2|H)/ P(E1 n E2)
Navie Bayes 알고리즘
1) multinonial Navie Bayes
-> descrete
-> feacture의 state가 여러개
2) Gianussian Navie Bayes -> Normal distnitbution N( 뮤 , STD)
-> Contionuous
