comment pandas multiindex assignment from another dataframe
I see that's a good explanation, thanks. I like the df_.values, especially because it allows you to do all kinds of crazy partial assignments. Just need to be careful to index the data frames in the same order, I was wondering why some of my data suddenly flips around (oops).

comment Topic Modelling in MALLET vs NLTK
If you're using gensim you might as well go with the online lda version in gensim.models.ldamodel.LdaModel instead of the mallet one, unless you really really want to use the Gibbs sampling variety that mallet implements.
