Algorithm

public abstract class AbstractPrimitiveDistanceBasedAlgorithm<O,R extends Result>
extends AbstractAlgorithm<R>

Abstract base class for distance-based algorithms that need to work with synthetic objects such as mean vectors. This class only allows distances that are defined on arbitrary objects, not only database objects!
