NMFNonsmoothUpdateInitialFactors Method

Provides the initial factors for the iteration process that computes W and H in the non-negative matrix factorization V = WH.

Namespace:  CenterSpace.NMath.Core
Assembly:  NMath (in NMath.dll) Version: 7.3
Syntax
public void InitialFactors(
	ref DoubleMatrix V,
	int k,
	ref DoubleMatrix W,
	ref DoubleMatrix H
)

Parameters

V
Type: CenterSpace.NMath.CoreDoubleMatrix
The non-negative matrix being factored
k
Type: SystemInt32

W
Type: CenterSpace.NMath.CoreDoubleMatrix
The first factor. Should be V.Rows x k
H
