Cluster validation is one of the main topics in data clustering; this problem consists in finding and objective criterion to determine how good a partition generated by the clustering algorithm is.

As shown in the previous subsection, data clustering enables us to identify the discrete states ({[q.sub.1], [q.sub.2], ..., [q.sub.m]}) and to label each data point in D with the corresponding discrete state.
