Fuzzy regression: a genetic programming approach
(Citations: 2)
Given some data pairs (X¯i, Y¯i), 1⩽i⩽k, of fuzzy numbers, we are interested in finding a fuzzy function F which best fits the given data. Because of fuzzy arithmetic, we cannot compute a fuzzy function with F(X¯i)=Y¯ i for all i, as in the crisp case. Therefore, we used a genetic programming approach to find a suitable fuzzy function. We present some tests and argue that this method is quite suitable for obtaining a fuzzy function which can explain the given data
