INMFUpdateAlgorithm Interface 
Namespace: CenterSpace.NMath.Core
The INMFUpdateAlgorithm type exposes the following members.
Name  Description  

Cost 
Returns the value of the cost function for the nonnegative
factorization of V = WH. The cost function is minimized by
the factorization.
 
InitialFactors 
Provides the initial factors for the iteration process that
computes W and H in the nonnegative matrix factorization
V = WH.
 
IterationStep 
Updates the factors W and H in the nonnegative matrix factorization
V = WH.

C(V, W, H)  C(V, W, H) = V  WH
