Detailed Description

Cluster is the abstract base class for cluster hierarchy.

This class can both identify and run a cluster. The H in front of distance functions means that that distance is used for the hierarchical version of the algorithm

Member Function Documentation

double CLUS::Cluster::AdjustPrototypes (  void   )  [inline]
 

Finalizes one big step of the identification process.

Computes the new prototype of the cluster and returns the distance between the old and the new prototype so a decision if the proces should continue can be taken
