Description

Interface Summary

Distance<D extends Distance<D>>	The interface Distance defines the requirements of any instance class.
MeasurementFunction<O extends DatabaseObject,D extends Distance<D>>	Interface Measurement describes the requirements of any measurement function (e.g. distance function or similarity function), that provides a measurement for comparing database objects.
PreprocessorBasedMeasurementFunction<O extends DatabaseObject,P extends Preprocessor<O>,D extends Distance<D>>	Describes the requirements of any measurement function (e.g. distance function or similarity function) needing a preprocessor running on a database.

Class Summary

AbstractDistance<D extends AbstractDistance<D>>	An abstract distance implements equals conveniently for any extending class.
AbstractMeasurementFunction<O extends DatabaseObject,D extends Distance<D>>	Abstract implementation of interface MeasurementFunction that provides some methods valid for any extending class.
BitDistance	Provides a Distance for a bit-valued distance.
CorrelationDistance<D extends CorrelationDistance<D>>	The correlation distance is a special Distance that indicates the dissimilarity between correlation connected objects.
DistanceUtil	Class with distance related utility functions.
DoubleDistance	Provides a Distance for a double-valued distance.
FloatDistance	Provides a Distance for a float-valued distance.
IntegerDistance	Provides an integer distance value.
NumberDistance<D extends NumberDistance<D,N>,N extends Number>	Provides a Distance for a number-valued distance.
PreferenceVectorBasedCorrelationDistance	A PreferenceVectorBasedCorrelationDistance holds additionally to the CorrelationDistance the common preference vector of the two objects defining the distance.
SubspaceDistance	The subspace distance is a special distance that indicates the dissimilarity between subspaces of equal dimensionality.
