The NMFClustering<(Of <(Alg>)>) type exposes the following members.
Constructors
| Name | Description | |
|---|---|---|
| NMFClustering<(Of <(Alg>)>) | Overloaded. |
Methods
| Name | Description | |
|---|---|---|
| Equals | (Inherited from Object.) | |
| Factor | Overloaded. | |
| GetHashCode |
Serves as a hash function for a particular type.
(Inherited from Object.) | |
| GetType |
Gets the Type of the current instance.

| ToString | (Inherited from Object.) |
Fields
| Name | Description | |
|---|---|---|
| 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
| Name | Description | |
|---|---|---|
| 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
ConvergenceCheckPeriod | |
| 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
