Clusters the data into the specified number of clusters.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4

Syntax

public ClusterSet Cluster(
	int k,
	RandGenMTwist rnd
)

Public Function Cluster ( 
	k As Integer,
	rnd As RandGenMTwist
) As ClusterSet

public:
ClusterSet^ Cluster(
	int k, 
	RandGenMTwist^ rnd
)

member Cluster : 
        k : int * 
        rnd : RandGenMTwist -> ClusterSet

Parameters

k Int32: The number of clusters to form.
rnd RandGenMTwist: Random number generator.

Return Value

ClusterSet
A ClusterSet that identifies the cluster into which each object was grouped. Cluster numbers are based on row indices in this.Data and this.Centers.

Exceptions

Exception	Condition
InvalidArgumentException	Thrown if k is less than one or greater than the number of objects (this.N).
NMathException	Thrown if an empty cluster is encountered. Re-cluster with different starting centers.

Remarks

A random set of distinct rows in this.Data are chosen as the initial centers.
