	IEquatable<NonnegativeMatrixFactorizationBase>

The NonnegativeMatrixFactorizationBase type exposes the following members.

Constructors

	Name	Description
	NonnegativeMatrixFactorizationBase	Initializes a new instance of the NonnegativeMatrixFactorizationBase class

Properties

	Name	Description
	InitializationMethod	Gets or sets the initialization method to be used for the factorization.
	MaximumNumberOfIterations	Gets the maximum number of iterations for the factorization algorithm.
	NumberOfAdditionalTrials	Gets the number of additional trials to perform with a random initialization.

Methods

	Name	Description
	Factorize	Factorizes the input matrix X into a product of two matrices with the specified rank.
	FactorizeOneTrial	Factorizes a non-negative matrix V into non-negative factors W and H.
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	TraceOfTransposeAndMultiply	Calculates the trace of the product of the transposed matrix A with B: trace(AᵀB).
