It would be necessary to implement IDF transforms, and possibly expose a TfidfVectorizer estimator.
This requires selecting a sparse array library. For now, we use custom CSRArray structs to represent CSR arrays. https://github.com/vbarrielle/sprs is a good candidate but this needs more investigation in any case.
