Interface KMedoidsInitialization<V>

Type Parameters:

V - Object type

All Known Implementing Classes:

FarthestPointsInitialMeans, FirstKInitialMeans, KMeansPlusPlusInitialMeans, PAMInitialMeans, RandomlyChosenInitialMeans

public interface KMedoidsInitialization<V>

Interface for initializing K-Medoids. In contrast to k-means initializers, this initialization will only return members of the original data set.
