Interface HierarchicalClusterer<E>

Type Parameters:

E - the type of objects being clustered

All Superinterfaces:

Clusterer<E>

All Known Implementing Classes:

AbstractHierarchicalClusterer, CompleteLinkClusterer, SingleLinkClusterer

public interface HierarchicalClusterer<E>
extends Clusterer<E>

The HierarchicalClusterer interface defines a means of clustering a set of objects into a hierarchy of clusters.

The class Dendrogram is used to represent the results of a hierarchical clustering. From a dendrogram, it is possible to retrieve clusterings as sets of sets as defined in the super-interface Clusterer. These clusterings may be retrieved by requiring clusters to have elements within a given distance, or by taking the best k clusters. See the Dendrogram class documentation for more information, as well as the hieararchical clusterer implementations, which explain how they implement Clusterer in terms of HierarchicalClusterer.
