DunnIndex
public DunnIndex()
- Create an instance of this index.
calculateWithinClusterScatter
protected double calculateWithinClusterScatter(int k)
-
- Specified by:
calculateWithinClusterScatter
in class ScatterSeperationRatio
calculateBetweenClusterSeperation
protected double calculateBetweenClusterSeperation(int i,
int j)
-
- Specified by:
calculateBetweenClusterSeperation
in class ScatterSeperationRatio
getClone
public DunnIndex 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.
