All Known Implementing Classes:

ColorClustering

public interface Clustering

An interface to build clusterings.

Author:

Method Summary

Modifier and Type	Method and Description
Cluster	getCluster(java.lang.Object o) Returns the cluster which is the most similar to the given parameter.
Cluster[]	getClusters() Returns all clusters of this clustering.
int	getK() The number of clusters to this clustering. k might differ from the getClusters().length, when empty clusters (clusters with no members) are automatically removed.
java.lang.Float	getLoss() Returns the loss of the clustering (= mean loss of all clusters).

Method Detail

getLoss

java.lang.Float getLoss()

Returns the loss of the clustering (= mean loss of all clusters).

Returns:

The loss of the clustering.

getK

int getK()

The number of clusters to this clustering. k might differ from the getClusters().length, when empty clusters (clusters with no members) are automatically removed.

Returns:

The number of clusters.

getClusters

Cluster[] getClusters()

Returns all clusters of this clustering.

Returns:

The clusters.

getCluster

Cluster getCluster(java.lang.Object o)

Returns the cluster which is the most similar to the given parameter.

Parameters:

o - An element.

Returns:

The most similar cluster to the input or null if the input is not compatible to the data type of the cluster members.
