StreamingKMeans.StreamingKMeansClustering

public StreamingKMeans.StreamingKMeansClustering(double alpha,
                                         double beta,
                                         double gamma,

                                         double logNumPoints)

Creates a new instance of online KMeans clustering.

Method Detail

addVector

public int addVector(T value)

Adds value a cluster. The cluster may exist already or a new one may be generated. A unique identifier for the vector being clustered is returned. This identifier is to be used later on to query the cluster to which the value was assigned.

Specified by:

addVector in interface OnlineClustering<T extends DoubleVector>

getCluster

public Cluster<T> getCluster(int clusterIndex)

Returns the Cluster with id clusterIndex.

Specified by:

getCluster in interface OnlineClustering<T extends DoubleVector>

getClusters

public List<Cluster<T>> getClusters()

Returns the list of all Clusters.

Specified by:

getClusters in interface OnlineClustering<T extends DoubleVector>

size

public int size()

Returns the numeber of Clusters.

Specified by:

size in interface OnlineClustering<T extends DoubleVector>

toString

public String toString()

Returns a string describing this ClusterMap.

Overrides:

toString in class Object
