Class ClusteringMatrixBuilder

java.lang.Object

ch.usi.inf.sape.hac.ClusteringMatrixBuilder

All Implemented Interfaces:

ClusteringBuilder

public final class ClusteringMatrixBuilder
extends Object
implements ClusteringBuilder

A ClusteringMatrixBuilder builds a matrix in which each row represents a step in the clustering and each column represents an observation or cluster. In the first step (row 0), each column represents an observation. In the last step, each column refers to the same cluster. Each step represents a copy of the step above, with two clusters merged into one.
