WebFormal Definition of membership function Let us consider fuzzy set A, A = {(x, µA(x)) x Є X} where µA(x) is called the membership function for the fuzzy set A. X is referred to as the universe of discourse. The membership function associates each element x Є X with a value in the interval [0, 1]. WebFuzzy Logic is defined via a membership function that measures the degree to which a particular element is a member of a set. The membership function can take any value between 0 and 1 inclusive.
