Uses of AbstractDatabaseDistance in elki.distance

Subclasses of AbstractDatabaseDistance in elki.distance

Modifier and Type	Class	Description
class	AbstractDBIDRangeDistance	Abstract base class for distance functions that rely on integer offsets within a consecutive range.
class	AbstractIndexBasedDistance<O,F extends IndexFactory<O>>	Abstract super class for distance functions needing a database index.
class	RandomStableDistance	This is a dummy distance providing random values (obviously not metrical), useful mostly for unit tests and baseline evaluations: obviously this distance provides no benefit whatsoever.
class	SharedNearestNeighborJaccardDistance<O>	SharedNearestNeighborJaccardDistance computes the Jaccard coefficient, which is a proper distance metric.
