Coevolutionary design of Takagi-Sugeno fuzzy systems

Abstract

This paper suggests a coevolutionary approach to design Takagi-Sugeno fuzzy models. The coevolutionary process induces cooperation among individuals of genetically different populations, the species. Populations from four species represent partial solutions to the fuzzy modeling problem. Cooperation is also achieved via fitness sharing, once the fitness of an individual depends on the fitness of individuals of different species. The performance of the proposed approach is evaluated using a function approximation problem with noisy data, and a classification problem.
