Update rules for the Non-negative Matrix Factorization. This follows a method described in the paper 'Algorithms for Non-negative Matrix Factorization' by D. D. Lee and H. S. Seung. This is a multiplicative rule that ensures that the Kullback–Leibler divergence is non-increasing between subsequent iterations. Both of the update rules for W and H are defined in this file.
