SYNOPSIS
nmf [h] [v] H string i string r int W string [m int] [e double] [s int] [u string] V
DESCRIPTION
This program performs nonnegative matrix factorization on the given dataset, storing the resulting decomposed matrices in the specified files. For an input dataset V, NMF decomposes V into two matrices W and H such that
V = W * H
where all elements in W and H are nonnegative. If V is of size (n x m), then W will be of size (n x r) and H will be of size (r x m), where r is the rank of the factorization (specified by rank).
Optionally, the desired update rules for each NMF iteration can be chosen from the following list:

 multdist: multiplicative distancebased update rules (Lee and Seung 1999)
 multdiv: multiplicative divergencebased update rules (Lee and Seung 1999)
 als: alternating least squares update rules (Paatero and Tapper 1994)
The maximum number of iterations is specified with max_iterations, and the minimum residue required for algorithm termination is specified with min_residue.
REQUIRED OPTIONS
 h_file (H) [string]
 File to save the calculated H matrix to.
 input_file (i) [string]
 Input dataset to perform NMF on.
 rank (r) [int]
 Rank of the factorization.
 w_file (W) [string]
 File to save the calculated W matrix to.
OPTIONS
 help (h)
