The NMFClustering<(Of <(Alg>)>) type exposes the following members.

Constructors

  NameDescription
NMFClustering<(Of <(Alg>)>)Overloaded.

Methods

  NameDescription
Equals
Determines whether the specified Object is equal to the current Object.
(Inherited from Object.)
FactorOverloaded.
GetHashCode
Serves as a hash function for a particular type.
(Inherited from Object.)
GetType
Gets the Type of the current instance.
(Inherited from Object.)
ToString
Returns a String that represents the current Object.
(Inherited from Object.)

Fields

  NameDescription
DEFAULT_CONV_CHECK_PEROID
The default number if iterations between checks for convergence.
DEFAULT_MAX_FACTORIZATION_ITERATIONS
The default maximum number of iterations to perform.
DEFAULT_STOPPING_ADJACENCY
The default value for the stopping adjacency. The stopping adjacency is the number of consecutively unchanged connection matrices that must be observed before convergence.

Properties

  NameDescription
ClusterSet
Gets a ClusterSet object that identifies the cluster into which each object was grouped. The indexing operator on the returned ClusterSet returns the cluter number to which ith object was grouped.
Connectivity
Gets the adjacency matrix. The Adjacency Matrix is a symmetric matrix whose i, jth value is 1 if columns i and j of the factored matrix are in the same cluster, and 0 if they are not.
Converged
Returns true if the factorization algorithm converged. Returns false if the maximum number of iterations was exceeded before convergence was achieved.
ConvergenceCheckPeriod
Gets and sets the convergence check period. Convergence will be checked every

iterations.
Cost
Gets the value of the cost function for the factorization. The cost function is the function that is minimized by the NMF updater algorithm used.
H
Gets the matrix H in the NMF factorization of V, V ~ WH
Iterations
Gets the total number of iterations performed in the most recent calculation.
MaxFactorizationIterations
Gets and sets the maximum number of iterations to perform.
StoppingAdjacency
Gets and sets the stopping adjacency. The stopping adjacency. The stopping adjacency is the number of consecutively unchanged connection matrices that must be observed before convergence.
Updater
Gets ans sets the NMF iteration algorithm to use.
W
Gets the matrix W in the NMF factorization of V, V ~ WH
