Hi friends, I am making a project where I have to make use of NMF (non-negative matrix factorization). But there's a problem I'm facing. Its been quite some time since I studied any maths. I am getting to understand NMF slowly but it does not seem to be working. I have a few questions: 1. Kindly tell me some good resources to study NMF and LNMF from. I would prefer resources that start from scratch. 2. Whats the real intuitive/graphical meaning of the multiplicative update functions? O! I forget to mention. I only have to study NMF for minimizing Euclidean distance and KL Divergence. I understand well through graphs. I need conceptual information on how this stuff works. Thanking in anticipation.
