Generating linguistic fuzzy rules for pattern classification with genetic algorithms

摘要

this paper presents a new genetic-based approach to automatically extracting classification knowledge from numerical data by means of premise learning.A genetic algorithm is utilized to search for premise structure in combination with parameters of membership functions of input fuzzy set to yield optimal conditions of classification rules.The consequence under a specific condition is determined by choosing from all possible candidates the class which lead to a maximal truth value of the rule.the major advantage of our work is that a parsimonious knowledge base with a low number of classification rules is made possible.the effectiveness of the proposed method kis demonstrated by the simulation results on the Iris data.
