How to use TF-IDF in Multinomial Naive Bayes? I want to know like at which step it should be used.At which step of Naive Bayes we should be performing Normalisation?
TF-IDF Use case
Hey @fguglani
Typically, we would use Word Counts as the input to a Multinomial Naive Bayes model. The shape of such data is: (No of Samples, Size of Vocab).
The output given by TF-IDF is also of the same shape and can be used as a direct replacement of the Word Count data matrix. Rest all things remain the same for such a replacement.
Hope this helps!
