✦ Synopsis

In this paper we present different approaches to the problem of fuzzy rules extraction by using a combination of fuzzy clustering and genetic algorithms as the main tools. This combination of techniques let us define a hybrid system by which we can have different approaches in a fuzzy modeling process. For example, we can obtain a first approximation to the fuzzy rules that describe the system behavior represented by a collection of raw data, without any assumption about the structure of the data using a fuzzy clustering technique, and subsequently, these rules can be tuned using a genetic algorithm. Alternatively, this genetic algorithm can be used in order to generate and tune the fuzzy rules directly from the data with or without some priori information. Finally, their performances are compared.

This paper presents an approach to building multi-input and single-output fuzzy models. Such a model is composed of fuzzy implications, and its output is inferred by simplified reasoning. The implications are automatically generated by the structure and parameter identification. In structure identif

In this article, we present a formalism for embedding fuzzy logic into object-oriented methodology in order to deal with the uncertainty and vagueness that pervade knowledge and object descriptions in the real world. We show how fuzzy logic can be used to represent knowledge in conventional objects,

A new kind of mapping rule base scheme is proposed to get the fuzzy rules of hierarchical fuzzy systems. The algorithm of this scheme is developed such that one can easily design the involved fuzzy rules in the middle layers of the hierarchical structure. In contrast with the conventional single lay
