Identifying fuzzy models utilizing genetic programming

نویسنده

  • Andreas Bastian
چکیده

Fuzzy models o er a convenient way to describe complex nonlinear systems. Moreover, they permit the user to deal with uncertainty and vagueness. Due to these advantages fuzzy models are employed in various elds of applications, e.g. control, forecasting, and pattern recognition. Nevertheless, it has to be emphasized that the identi cation of a fuzzy model is a complex optimization task with many local minima. Genetic programming provides a way to solve such complex optimization problems. In this work, the use of genetic programming to identify the input variables, the rule base and the involved membership functions of a fuzzy model is proposed. For this purpose, several new reproduction operators are introduced. c © 2000 Elsevier Science B.V. All rights reserved

CREDIBILITY-BASED FUZZY PROGRAMMING MODELS TO SOLVE THE BUDGET-CONSTRAINED FLEXIBLE FLOW LINE PROBLEM

This paper addresses a new version of the exible ow line prob- lem, i.e., the budget constrained one, in order to determine the required num- ber of processors at each station along with the selection of the most eco- nomical process routes for products. Since a number of parameters, such as due dates, the amount of available budgets and the cost of opting particular routes, are imprecise (fuzz...

Constructive Induction of Fuzzy Cartesian Granule Feature Models using Genetic Programming

The G_DACG (Genetic Discovery of Additive Cartesian Granule feature models) constructive induction algorithm is presented as a means of automatically identifying rulebased Cartesian granule feature models from example data. G_DACG combines the powerful search capabilities of genetic programming with a rather novel and cheap fitness function based upon the semantic separation of learnt concepts ...

Constructive Induction of Fuzzy Cartesian Granule Feature Models using Genetic Programming with applications

Cartesian granule features are derived features that are formed over the cross product of words that linguistically partition the universes of the constituent input features. Both classification and prediction problems can be modelled quite naturally in terms of Cartesian granule features incorporated into rule-based models. The induction of Cartesian granule feature models involves discovering...

A Genetic Programming-based Scheme for Solving Fuzzy Differential Equations

This paper deals with a new approach for solving fuzzy differential equations based on genetic programming. This method produces some trial solutions and seeks the best of them. If the solution cannot be expressed in a closed analytical form then our method produces an approximation with a controlled level of accuracy. Furthermore, the numerical results reveal the potential of the proposed appr...
