Zadeh was born in Baku, Azerbaijan SSR, [18] as Lotfi Aliaskerzadeh. [19] His father was Rahim Aleskerzade, an Iranian Muslim Azerbaijani [ 20 ] journalist from Ardabil on assignment from Iran, and his mother was Fanya (Feyga [ 21 ] ) Korenman, a Jewish pediatrician from Odesa, Ukraine , who was an Iranian citizen.
Fuzzy sets were introduced independently by Lotfi A. Zadeh in 1965 as an extension of the classical notion of set. [1] [2] At the same time, Salii (1965) defined a more general kind of structure called an "L-relation", which he studied in an abstract algebraic context; fuzzy relations are special cases of L-relations when L is the unit interval ...
Lotfi A. Zadeh rejected such an interpretation, on the ground that in many human endeavours as well as technologies it is highly important to define more exactly "to what extent" something is applicable or true, when it is known that its applicability can vary to some important extent among large populations. Reasoning which accepts and uses ...
The term fuzzy logic was introduced with the 1965 proposal of fuzzy set theory by mathematician Lotfi Zadeh. [2] [3] Fuzzy logic had, however, been studied since the 1920s, as infinite-valued logic—notably by Łukasiewicz and Tarski. [4] Fuzzy logic is based on the observation that people make decisions based on imprecise and non-numerical ...
It started in 1965 after the publication of Lotfi Asker Zadeh's seminal work Fuzzy sets. [1] Linguistics is an example of a field that utilizes fuzzy set theory. Definition
It uses measures of possibility and necessity between 0 and 1, ranging from impossible to possible and unnecessary to necessary, respectively. Professor Lotfi Zadeh first introduced possibility theory in 1978 as an extension of his theory of fuzzy sets and fuzzy logic. Didier Dubois and Henri Prade further contributed to its development.
The answer to this question was provided in 1975 by the inventor of fuzzy sets, Lotfi A. Zadeh, [1] when he proposed more sophisticated kinds of fuzzy sets, the first of which he called a "type-2 fuzzy set". A type-2 fuzzy set lets us incorporate uncertainty about the membership function into fuzzy set theory, and is a way to address the above ...
Lotfi Zadeh describes an information fusion problem. [3] A patient has an illness that can be caused by three different factors A, B or C.Doctor 1 says that the patient's illness is very likely to be caused by A (very likely, meaning probability p = 0.95), but B is also possible but not likely (p = 0.05).
