NMFMultiplicativeUpdateInitialFactors 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: 7.4
public void InitialFactors(
	ref DoubleMatrix V,
	int k,
	ref DoubleMatrix W,
	ref DoubleMatrix H


V  DoubleMatrix
The non-negative being factored
k  Int32
The number of columns in W and the number of rows in H
W  DoubleMatrix
The first factor. Should be V.Rows x k
H  DoubleMatrix
The second factor. Should be k x V.Cols
