Subject Re: Mahout LDA Parameter: maxIter

I agree it is not very friendly. Impossible to tell the correct value in 
the options section processing. It needs to be >= than the actual number 
of unique terms in the corpus and that is hard to anticipate though I 
think it is known in seq2sparse. If it turns out to be the dictionary 
size (I'm investigating), then it could be computed by adding a 
dictionary path argument instead of the current option. Trouble with 
that is the dictionary is not needed for anything else by LDA.
