Some popular approaches include to determining the cluster combination which minimizes the Fuzzy Performance Index (FPI) or Modified partition Entropy (MPE).
The MPE establishes the degree of fuzziness created by a specified number of clusters for a defined exponent value.
The notion is that the smaller the MPE, the more suitable is the corresponding number of clusters at the given exponent value.
