Aug 21, 2021 at 10:15 comment added Tim @Esha this is maximum likelihood. In the documentation, they are saying that they use MAP so consider also priors.
Aug 21, 2021 at 10:07 comment added Esha I am sorry, I don't quite understand... Why can't we estimate parameters through training data? Say we are building a email spam classifier using Naive Bayes. We have training data as 10000 emails. Now we pick all the spam mails (which is variable y) and calculate how many times a word (which is variable π‘₯𝑖) is appearing in those mails. This would give us the probability 𝑃(π‘₯𝑖|𝑦). Where am I going wrong?
