Gensim can process arbitrarily large corpora, using data-streamed algorithms. There are no "dataset must fit in RAM" limitations. Platform independent Gensim runs on Linux, Windows and OS X, as well as any other platform that supports Python and NumPy. ...
Each of the $$M$$ topics is represented by a vector of length $$V$$ that details which words are likely to occur, given a document on that topic. So for topic 1, 'learning', 'modelling' and 'statistics' might be some of the most common words. This means that you could then say...
