CachedDissimilarityMetricTInstance Class | |
Represents a cache to store dissimilarities between all instances of a known set, as dictated by a base
IDissimilarityMetricTInstance.

Remarks
This class is useful to use during the execution of AgglomerativeClusteringAlgorithmTInstance as many
ILinkageCriterionTInstance classes rely on pair-wise dissimilarities between the
instances.
In that sense, the set of instances has to be known beforehand and must not change and no verification is done in
Calculate(TInstance, TInstance).
This means that if cluster centroids are used to measure dissimilarities, they have to be included in the original
set, otherwise the value will not be present in the cache.
