Copy

public virtual void Factor(
	DataFrame data,
	int k,
	DoubleMatrix W,
	DoubleMatrix H
)

Public Overridable Sub Factor ( 
	data As DataFrame,
	k As Integer,
	W As DoubleMatrix,
	H As DoubleMatrix
)

public:
virtual void Factor(
	DataFrame^ data, 
	int k, 
	DoubleMatrix^ W, 
	DoubleMatrix^ H
)

abstract Factor : 
        data : DataFrame * 
        k : int * 
        W : DoubleMatrix * 
        H : DoubleMatrix -> unit 
override Factor : 
        data : DataFrame * 
        k : int * 
        W : DoubleMatrix * 
        H : DoubleMatrix -> unit

Parameters

data DataFrame: The matrix to be factored.
k Int32: The number of columns in W (and rows in >H).
W DoubleMatrix: Initial value for W. If the matrix to factored is m x n then W must be m x k.
H DoubleMatrix: Initial value for H. If the matrix to be factored is m x n then H must be k x n.
