Type Parameters:

O - type of DatabaseObjects handled by this Algorithm

All Implemented Interfaces:

Algorithm<O>, Clustering<O>, Loggable, Parameterizable

public class FourC<O extends RealVector<O,?>>
extends ProjectedDBSCAN<O>

4C identifies local subgroups of data objects sharing a uniform correlation. The algorithm is based on a combination of PCA and density-based clustering (DBSCAN).
