Linguistic terms in fuzzy logic
NettetWe have studied that fuzzy logic uses linguistic variables which are the words or sentences in a natural language. For example, if we say temperature, it is a linguistic variable; the values of which are very hot or cold, slightly hot or cold, very warm, slightly warm, etc. The words very, slightly are the linguistic hedges. Nettet11. des. 2016 · In linguistics, the meaning of a vague or imprecise expression is a fuzzy set in the proper sense. What we call fuzzy semantics is an approach that uses fuzzy logic (Zadeh’s sense) to express the fuzziness of the meaning. 2.2. Computing with Words and Fuzzy Logic

NettetThe robust nature of fuzzy logic rules in applications compensates for the simplistic representation of linguistic variables. The Anatomy of a Fuzzy Rule IF room IS cold THEN heat IS on; Each fuzzy rule consists of two parts: a predicate and consequence part. The predicate determines the rule weight or truth. NettetThe fuzzy logic, or fuzzy set theory, aims to represent fuzzy concepts in an understandable form. It links natural language with reasoning computing system (e.g., soft computing system) through the use of linguistic variables and quantifiers. Linguistic variables can represent words such as “age”, “tall”, “hard”, “street length ...
NettetFuzzy logic approach is a methodology mainly used to solve the issues related to multifaceted and difficult to understand quantitatively by using fuzzy set theory [1]. Fuzzy set methods permit to capture the undefined and imprecise systems of the real world by using linguistic terms so that computers can follow human thought processes [2]. NettetFuzzy logic works on the concept of deciding the output based on assumptions. It works based on sets. Each set represents some linguistic variables defining the possible state of the output. Each possible state of the input and the degrees of change of the state are a part of the set, depending upon which the output is predicted.
http://cs.bilkent.edu.tr/~zeynep/files/short_fuzzy_logic_tutorial.pdf Classical logic only permits conclusions that are either true or false. However, there are also propositions with variable answers, such as one might find when asking a group of people to identify a color. In such instances, the truth appears as the result of reasoning from inexact or partial knowledge in which the sampled answers are mapped on a spectrum. Both degrees of truth and probabilities range between 0 and 1 and hence may seem similar at firs…

The mapping then provides a basis from which decisions can be made, or patterns discerned. The process of fuzzy inference involves all the pieces that are described in Membership Functions, Logical Operations, and If-Then Rules. how rare is green and yellow eyesNettetAuthors: Badredine Arfi.
