✦ Synopsis


We first argue that the extension principle is too computationally involved to be an efficient way for a computer to evaluate fuzzy functions. We then suggest using c~-cuts and interval arithmetic to compute the values of fuzzy functions. Using this method of computing fuzzy functions, we then show that neural nets are universal approximators for (computable) fuzzy functions, when we only input non-negative, or non-positive, fuzzy numbers.

We show how to construct a large class of universal approximators for fuzzy functions (which continuously map fuzzy numbers into fuzzy numbers and are the extension principle extensions of continuous real-valued functions). One important application is that layered, feedforward, neural nets, with re

One of the reasons why fuzzy methodology is successful is that fuzzy systems are universal approximators, i.e., we can approximate an arbitrary continuous function within Ε½ . any given accuracy by a fuzzy system. In some practical applications e.g., in control , it is Ε½ desirable to approximate not
