Returns a deep copy of self.

Returns the value of the cost function for the non-negative factorization of V = WH. The cost function is minimized by the factorization.

Determines whether the specified Object is equal to the current Object.

Serves as a hash function for a particular type.

Gets the Type of the current instance.

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

Updates the factors W and H in the non-negative matrix factorization V = WH.

Returns a String that represents the current Object.
