A New Index for Clustering Evaluation Based on Density Estimation. (arXiv:2207.01294v3 [cs.LG] UPDATED)

A new index for internal evaluation of clustering is introduced. The index is
defined as a mixture of two sub-indices. The first sub-index $ I_a $ is called
the Ambiguous Index; the second sub-index $ I_s $ is called the Similarity
Index. Calculation of the two sub-indices is based on density estimation to
each cluster of a partition of the data. An experiment is conducted to test the
performance of the new index, and compared with six other internal clustering …
