Is there good library to do nonnegative matrix fac

Question

I have a sparse matrix whose shape is 570000*3000. I tried nima to do NMF (using the default nmf method, and set max_iter to 65). However, I found nimfa very slow. Have anyone used a faster library to do NMF?

Answer 1

I have used libNMF before. It's written in C and is very fast. There is a paper documenting the algorithm and code.

The paper also lists several alternative packages for NMF (in bunch of different languages (which I have copied here for future reference).
