Rough Sets and Fuzzy Logic

We present two new fuzzy cluster validity functionals (minimum and mean hard tendencies), based on the analysis of the hard tendency of the fuzzy classification generated by the fuzzy c-means algorithm. We have used the bootstrap technique, to avoid the possible influence of local minimums, obtained by the fuzzy c-means algorithm.
