Fuzzy Logic

Introduction 3 Fuzzy concepts first introduced by Zadeh in the 1960s and 70s Traditional computational logic and set theory is all about true or false zero or one in or out (in terms of set membership) black or white (no grey) Not the case with fuzzy logic and fuzzy ,...

FUZZY LOGIC & FUZZY SETS

3 What is fuzzy thinking? Experts rely on common sense when they solve problems How can we represent expert knowledge that uses vague and ambiguous terms in a computer? Fuzzy logic is not logic that is fuzzy, but logic that is used to describe fuzziness Fuzzy logic is the theory of fuzzy sets, sets that calibrate vagueness...

Fuzzy logic

Fuzzy logic is a form of many-valued logic in which the truth values of variables may be any real number between 0 and 1 It is employed to handle the concept of partial truth, where the truth value may range between completely true and completely false By contrast, in Boolean logic, the truth values of variables may only be the integer values ,...

11 Fuzzy Logic

292 11 Fuzzy Logic Crisp sets are a special case of fuzzy sets, since the range of the function is restricted to the values 0 and 1 Operations defined over crisp sets, such as union or intersection, can be generalized to cover also fuzzy sets Assume as an example that X = {x1,x2,x3}...
