Fuzzy Rule - What is the fuzzy membership rule?


According to the fuzzy theory, a fuzzy set A in the universe X is defined by a function known as the membership function of set A. This has been discussed earlier. The function µA(x): X → [0, 1], where µA(x) = 1 if x is completely in A; µA(x) = 0 if x is not in A; and 0 < µA(x) < 1 if x is partially in A.
