Class IntraClusterDistance

java.lang.Object
  net.sourceforge.cilib.functions.Function
      net.sourceforge.cilib.functions.ContinuousFunction
          net.sourceforge.cilib.functions.clustering.ClusteringFitnessFunction
              net.sourceforge.cilib.functions.clustering.IntraClusterDistance

All Implemented Interfaces:

Serializable, Cloneable

public class IntraClusterDistance
extends ClusteringFitnessFunction

This clustering fitness function will probably never be used to train on directly. The main reason why it has been implemented is to be able to take measurements of the intra-cluster distance via the GenericFunctionMeasurement class. NOTE: By default, the cluster center refers to the cluster centroid. See ClusterCenterStrategy.

public IntraClusterDistance()

Method Detail

calculateFitness

public double calculateFitness()

Specified by:

calculateFitness in class ClusteringFitnessFunction

getClone

public IntraClusterDistance getClone()

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.
