Clusters are one per data point, while topics are not. So the model is
slightly different.
You can get the list of topics for each sample using NMF().fit_transform(X).

Hi everyone,
I am new to scikit. I only feel sad for not knowing it earlier - it's
awesome.
I am trying to do the following. Extract topics from a bunch of
tweets. I tried NMF (from the sample here -
http://scikit-learn.org/stable/auto_examples/applications/topics_extraction_with_nmf.html)
but I was not able to figure out how to list documents corresponding
to the extracted topics. Could someone please point me to an example
that lists the documents under each topic?
When I got stuck with NMF, I thought of using kmeans (min batch). I am
just wondering though if clustering is a reasonable approach for "topics".
I'd really appreciate any advice here.
Thanks,
Kashyap
