Study Notes
Fuzzy Logic Definition
- Fuzzy logic is a form of many-valued logic that allows for degrees of truth beyond the traditional binary true or false values.
History of Fuzzy Logic
- Fuzzy logic was introduced by Lotfi A. Zadeh in 1965.
Linguistic Variables
- Linguistic variables are variables whose values are words or sentences in a natural language.
- In fuzzy logic, linguistic variables are used to represent fuzzy concepts or categories.
Crisp vs Fuzzy Variables
- Crisp variables are variables with precise, sharp boundaries.
- Fuzzy linguistic variables are variables with imprecise, fuzzy boundaries.
Purpose of Fuzzy Logic
- The purpose of fuzzy logic is to represent variation or imprecision in logic and to provide a mathematical framework for dealing with uncertainty.
- Fuzzy logic aims to provide a way to reason approximately, rather than exactly, in situations where there is uncertainty or imprecision.
Role of Approximate Reasoning
- Approximate reasoning is a key aspect of fuzzy logic, allowing for the manipulation of fuzzy variables and the derivation of fuzzy conclusions.
Fuzzy Sets
- In the context of fuzzy logic, fuzzy sets are sets with fuzzy boundaries, allowing for membership degrees between 0 and 1, rather than the traditional 0 or 1.
- Fuzzy sets are used to represent fuzzy concepts or categories in a mathematical framework.
