Cluster validity
WebExternal Cluster Validity Measures and Pairwise Partition Similarity Scores Description. The functions described in this section quantify the similarity between two label vectors x and y which represent two partitions of a set of n elements into, respectively, K and L nonempty and pairwise disjoint subsets.. For instance, x and y can be two clusterings of … Web23.1.1.2 Ray and Turi’s Validity Measure. In [15] a measure of cluster validity is chosen as the ratio of intracluster distance to intercluster distance. The authors define these distances as Mintra = 1 nSSE(C) = 1 …
