Method Detail

perform

public void perform(ArrayList<T> objs,
                    Distance<T> d,
                    double dMax,
                    Aggregation<T> agg,
                    boolean closest,
                    ClusteringIndex<T> index)

Build clusters. Clusters are composed of objects that are at dMax distance of all others objects in the cluster.

Parameters:

objs - The objects list - the clusters have to be added there

d - The distance measure

dMax - The distance maximum value

agg - The aggregation method to use to define the cluster representations

performMST

public Collection<Collection<T>> performMST(Collection<Object> objs,
                                            Distance<Object> d,
                                            double dMax)
