Researches for universal approximation of fuzzy systems:a survey
Run Pei · Caai Transactions on Intelligent Systems · 2007
The universal approximation of fuzzy systems is an important direction of fuzzy theory.At present,a lot of progress has been made in the research for the universal approximation of fuzzy systems.In this paper,a survey of the universal approximation of fuzzy systems,the sufficient and necessary condition for fuzzy systems as universal approximators,and approximation accuracy of fuzzy systems etc is made in details.The achievement and properties(including advantages and disadvantages)of each method are also analyzed,and then the problems of the universal approximation of fuzzy systems in future researches are pointed out further.
