I'm looking for some LDA implementation. I know about this one, MALLET but it is coded in Java and I need some more performant.
Can someone give me some reference?
You can use the original C++ code of the LDA inventors Blei et al.
Also quite fast is GibbsLDA (written in C and C++).
If you want to parallelize it you might want to check out plda (C++).
