Day #34 - What is diffference between Logistics Regression and Naive Bayes


Both are probabilistic

Logistics
  • Discriminative (Entire approach is purely discriminative)
  • P(Y/X)
  • Final Value lies between Zero and 1
  • Formula given by exp(w0+w1x)/(exp(w0+ w1x)+1)
  • Further can be expressed as 1/(1+(exp-(w0+ w1x))
Naive Bayes
  • Generative Model
  • P(X/ Given Y) is Naive Bayes Assumption
  • Distribution for each class
