How to use TF-IDF when it is not categorical?

[sr13579]

Maybe I am asking a very 'noob' question. If the tfidf doesn't work with categorical data then how can I use it on a document?
Example tutorials are to find. Anyone here to help?

Hey @sr13579, TF-IDF works on token frequency vectors. You can transform blobs of text into token frequency vectors using either Word Count Vectorizer or Token Hashing Vectorizer.
