Implement online non-negative matrix factorization from http://www.cs.cornell.edu/~chenhao/pub/online-NMF.pdf

@larsmans added a nice (but non-scalable) NMF implementation to scikit-learn. Get inspiration/help from there, too: scikit-learn/scikit-learn#2537

Actually the NMF in scikit-learn is mostly @vene's work, I just optimized it.

There's been some talk about coordinate descent algorithms for NMF in scikit-learn.

Hi @souravsingh the best way to proceed is to apply to the RaRe incubator programme https://rare-technologies.com/incubator

Hi,

Couple of notes:

  1. the NMF implementation in scikit-learn has been replaced by a more scalable coordinate descent-based one a couple of releases ago (but it's not online/out-of-core)
  2. you might be interested in libmf (paper) which supports online parallel NMF among others.
