All Implemented Interfaces:

org.apache.hadoop.io.Writable, Cluster, Model<VectorWritable>, Parametered

Deprecated.

@Deprecated
public class Canopy
extends DistanceMeasureCluster

This class models a canopy as a center point, the number of points that are contained within it according to the application of some distance metric, and a point total which is the sum of all the points and is used to compute the centroid when needed.
