Remarks
In a non-negative factorization, a non-negative matrix, V,
is factored into a product, WH, of two non-negative matrices, W
and H. The algorithms pertaining to this interface compute this
factorization in an iterative manner, updating the factors W and
H at each step with the goal of minimizing some cost function. For
example:
CopyC#
CopyC#C(V, W, H) - C(V, W, H) = ||V - WH||
