Implementation of Multivariate Bernauli Naive Bayes

i see that the formula of this multivariate bernauli naive bayes is exactly same as that sir has covered in previous videos , by implementing it, so is there any need to implement it, as both are exactly same

Hey Shalini,
Multivariate Bernoulli Naive Bayes is specifically used for text data. And there are certain variations that are introduced in the same. Laplace Smoothening is one such variation which makes the implementation quite different. Both are, thus, not exactly same. And you must implement it.

I hope this helps.
