Interface Clusterer<E>

Type Parameters:

E - the type of objects being clustered

All Known Subinterfaces:

HierarchicalClusterer<E>

All Known Implementing Classes:

AbstractHierarchicalClusterer, CompleteLinkClusterer, KMeansClusterer, SingleLinkClusterer

public interface Clusterer<E>

The Clusterer interface defines a means of clustering a set of input elements

Typically, the clusters returned by a clusterer will form a partition of the input elements. This means that the clusters will be disjoint (that is, have an empty intersection), and that elements and foundElements will be equal after the following:

 Clusterer<E> clusterer = ...
 Set<E> elements = ...
 Set<Set<E>> clusters = clusterer.cluster(elements);
 Set<E> foundElements = new HashSet<E>();
 for (Set<E> cluster : clusters)
     foundElements.addAll(cluster);
 elements.equals(foundElements); // true
