This is the Turi Validity Index as given in Section 3.1.4 on page 66 of Mahamed G. H. Omran's PhD thesis, titled Particle Swarm Optimization Methods for Pattern Recognition and Image Processing, November 2004 NOTE: By default, the cluster center refers to the cluster centroid. See ClusterCenterStrategy.

Method Detail

calculateFitness

public double calculateFitness()

Specified by:

calculateFitness in class ClusteringFitnessFunction

getClone

public TuriIndex getClone()

Description copied from class: ContinuousFunction

Create a cloned copy of the current object and return it. In general the created copy will be a deep copy of the provided instance. As a result this operation an be quite expensive if used incorrectly.

Specified by:

getClone in interface Cloneable

Specified by:

getClone in class ClusteringFitnessFunction

Returns:

An exact clone of the current object instance.
