The Nonsmooth Nonnegative Matrix Factorization is defined as

V = WSH

where V, W, and H are the same as in the original NMF model. The positive symmetric matrix S is a "smoothing" matrix defined as:

            S = (1 - theta)I + (theta/q)11'
            

public double Theta { get; set; }

Public Property Theta As Double

public:
property double Theta {
	double get ();
	void set (double value);
}
