In astronomy, a particularly useful technique is nonnegative matrix factorization, since the flux of an astronomical source does not go negative. M Nmf - Python Repo Finally, we estimate the NMF topic model on the corpus of news articles, and we pick the number of topics to be 10: model = NMF(n_components=10, random_state=0) model.fit(dtm) The first line of code above constructs an NMF model using the function "NMF." The first input to the function is the number of topics which is set to "n_components . This NMF implementation updates in a streaming fashion and works best with sparse corpora.
