Abstract

Fuzzy integrals are very useful for fusing confidence or opinions from a variety of sources. These integrals are non-linear combinations of the support functions with the (possibly subjective) worth of subsets of the sources, realized by a fuzzy measure. There have been many applications and extensions of fuzzy integrals and this paper deals with a Sugeno integral where both the integrand and the measure take on fuzzy number values. A crucial aspect of using fuzzy integrals for fusion is determining or learning the measures. Here, we propose a genetic algorithm with novel cross-over and mutation operators to learn fuzzy-valued fuzzy measures for a fuzzy-valued Sugeno integral.
