Fuzzy Rule
What is fuzzy rule? How fuzzy reasoning is done in expert system? [5]
A fuzzy rule is an IF-THEN rule that uses fuzzy sets and linguistic variables instead of crisp (precise) values. It captures human-like reasoning by allowing partial truth values between 0 and 1. General Form: Example: Here, "HIGH", "FAST", "YOUNG", "LOW" a...
Full solved answer →Types of Fuzzy Expert Systems
Explain types of fuzzy expert systems in detail. [5]
A fuzzy expert system is a knowledge-based system whose knowledge is held as fuzzy IF-THEN rules and whose inference engine reasons with fuzzy logic instead of classical Boolean logic, so it can work directly with vague linguistic terms such as HIGH tempera...
Full solved answer →Discuss various types of fuzzy expert systems. [5]
A fuzzy expert system stores expert knowledge as fuzzy IF-THEN rules and reasons over them with fuzzy logic, which lets it handle linguistic and imprecise information that a Boolean expert system cannot express. All of them are rule-based and all of them fu...
Full solved answer →Fuzzy Reasoning
Discuss fuzzy reasoning process. [5]
Fuzzy reasoning (also called approximate reasoning or fuzzy inference) is a method of drawing conclusions from fuzzy premises using fuzzy logic. It extends classical logical reasoning to handle imprecise, vague, or uncertain information expressed in natural...
