IIndex(TInstance) Class


IIndexTInstance Class

Implements the I-index internal evaluation method [1] that uses the ratio of the separation and compactness of a given clustering partition scheme. To measure separation, it adopts the maximum distance between cluster centers and for compactness, the distance from an to its cluster center.
