Detailed Description

Author:

Mohan Rajendran

Initialization rule for Non-Negative Matrix Factorization. This simple initialization is performed by the random Acol initialization introduced in the paper 'Algorithms, Initializations and Convergence' by Langville et al. This method sets each of the columns of W by averaging p randomly chosen columns of V.
