DBIDRangeDistanceFunction
Distance functions valid in a static database context only (i.e. for
DBIDRanges)
For any "distance" that cannot be computed for arbitrary objects, only those
that exist in the database and referenced by their ID.
|
Modifier and Type | Class and Description |
---|---|
class |
AbstractDBIDRangeDistanceFunction
Abstract base class for distance functions that rely on integer offsets
within a consecutive range.
|
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.
|
Modifier and Type | Class and Description |
---|---|
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 |
FileBasedDoubleDistanceFunction
Distance function that is based on double distances given by a distance
matrix of an external ASCII file.
|
class |
FileBasedFloatDistanceFunction
Distance function that is based on float distances given by a distance matrix
of an external ASCII file.
