Modifier and Type | Class and Description |
---|---|
class |
AbstractDBIDRangeDistanceFunction
Abstract base class for distance functions that rely on integer offsets
within a consecutive range.
|
class |
AbstractIndexBasedDistanceFunction<O,F extends IndexFactory<O>>
Abstract super class for distance functions needing a database index.
|
class |
RandomStableDistanceFunction
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 |
SharedNearestNeighborJaccardDistanceFunction<O>
SharedNearestNeighborJaccardDistanceFunction computes the Jaccard
coefficient, which is a proper distance metric.
|
Modifier and Type | Class and Description |
---|---|
class |
AbstractSimilarityAdapter<O>
Adapter from a similarity function to a distance function.
|
class |
ArccosSimilarityAdapter<O>
Adapter from a normalized similarity function to a distance function using
arccos(sim) . |
class |
LinearAdapterLinear<O>
Adapter from a normalized similarity function to a distance function using
1 - sim . |
class |
LnSimilarityAdapter<O>
Adapter from a normalized similarity function to a distance function using
-log(sim) . |

---|---|
class |
DiskCacheBasedDoubleDistanceFunction
Distance function that is based on double distances given by a distance
matrix of an external binary matrix file.
|
class |
DiskCacheBasedFloatDistanceFunction
Distance function that is based on float distances given by a distance matrix
of an external binary matrix file.
|
class |
FileBasedSparseDoubleDistanceFunction
