Package elki.similarity

Similarity functions.

Interface Summary

Interface	Description
DBIDSimilarity	Interface DBIDSimilarity describes the requirements of any similarity function defined over object IDs.
IndexBasedSimilarity<O>	Interface for preprocessor/index based similarity functions.
IndexBasedSimilarity.Instance<T,I extends Index>	Instance interface for index/preprocessor based distance functions.
NormalizedPrimitiveSimilarity<O>	Marker interface for similarity functions working on primitive objects, and limited to the 0-1 value range.
NormalizedSimilarity<O>	Marker interface to signal that the similarity function is normalized to produce values in the range of [0:1].
PrimitiveSimilarity<O>	Interface Similarity describes the requirements of any similarity function.
Similarity<O>	Interface Similarity describes the requirements of any similarity function.
