Abstract EN

Clustering is a mostly unsupervised procedure and the majority of the clustering algorithms depend on certain assumptions in order to define the subgroups present in a data set.

As a consequence, in most applications the resulting clustering scheme requires some sort of evaluation as regards its validity.

In this paper, we present a clustering validity procedure, which evaluates the results of clustering algorithms on data sets.

We define a validity indexes, S_Dbw & SD, based on well-defined clustering criteria enabling the selection of the optimal input parameters values for a clustering algorithm that result in the best partitioning of a data set.

We evaluate the reliability of our indexes experimentally, considering clustering algorithm (K_Means) on real data sets.

Our approach is performed favorably in finding the correct number of clusters fitting a data set.
