Abstract

An approach of constructing interpretable and precise fuzzy classification system based on fuzzy clustering and genetic algorithm is proposed.First

the precision index is defined

and the necessary conditions of interpretability are analyzed.Second

the number of fuzzy rules is determined by cluster validity indices

and the initial fuzzy classification system is identified using a fuzzy clustering algorithm.Subsequently

the method of merging similar fuzzy sets is used to enhance the interpretability of the initial model.A genetic algorithm is used to improve the precision of the model.The process continues iteratively until the stop criteria are satisfied.The proposed approach is applied to the Iris benchmark classification problem

and the results show its validity.
