Speeding up Latent Dirichlet Allocation (LDA)

Alex has wrote a blog entry on the speed issue of LDA and released his fast LDA algorithm that performs on many computers. Here is the blog entry:

In Purdue's MLSS 2011, I was lucky to attend his lectures on graphical models. I like his lectures. The only regret is that I really hope he could give more details on LDA and its variants; for example, giving a detailed development on a variant of LDA models. But I understand the time was limited. After all, the lectures serve for a seminar, not for a college class.

  1. Thank you for introducing this implementation? It's exactly what I'm looking for.
