Evolution-based design of neural fuzzy networks using self-adapting genetic parameters

In this paper, an evolution-based approach to design of neural fuzzy networks is presented. The proposed strategy optimizes the whole fuzzy system with minimum rule number according to given specifications, while training the network parameters. The approach relies on an optimization tool, which combines evolution strategies and simulated annealing algorithms in finding the global optimum solution. The optimization variables include membership function parameters and rule numbers which are combined with genetic parameters to create diversity in the search space due to self-adaptation. The optimization technique is independent of the topology under consideration and capable of handling any type of membership function. The algorithmic details of the optimization methodology are discussed in detail, and the generality of the approach is illustrated by different examples
