Question

Fuzzy logic is usually represented as ___________

(a) IF-THEN-ELSE rules

(b) IF-THEN rules

(c) Both IF-THEN-ELSE rules & IF-THEN rules

(d) None of the mentioned

The question was asked in an online quiz.

This interesting question is from Fuzzy Logic in section Uncertain Knowledge and Reasoning of Artificial Intelligence

Answer 1

Right choice is (b) IF-THEN rules

To explain: Fuzzy set theory defines fuzzy operators on fuzzy sets. The problem in applying this is that the appropriate fuzzy operator may not be known. For this reason, fuzzy logic usually uses IF-THEN rules, or constructs that are equivalent, such as fuzzy associative matrices.

Rules are usually expressed in the form:

IF variable IS property THEN action
