Pedro Rodriguez commented on SPARK-5556:
----------------------------------------

I will read that paper, seems interesting. Probably worth discussing at some 
point, how is the philosophy behind supporting different algorithms? It seems 
like there are a good number (at least 2 Gibbs, 1 EM right now). On the same 
line of thought, perhaps it would be better to open two pull requests, one 
which refactors the current LDA to allow multiple algorithms, and a second for 
the Gibbs itself? Thoughts?
