Evidential c-means

A variant of the classical fuzzy c-means in the belief function framework. It is based on the concept of credal partition, extending those of hard, fuzzy and possibilistic ones. To derive such a structure, a suitable objective function is minimized using an alternating optimization algorithm similar to the fuzzy or possibilistic c-means algorithms. The method is described in:
