Early life and career

Azerbaijan

Zadeh was born in Baku, Azerbaijan SSR,[18] as Lotfi Aliaskerzadeh.[19] His father was Rahim Aleskerzade, an Iranian Muslim Azerbaijani journalist from Ardabil on assignment from Iran,[citation needed] and his mother was Fanya (Feyga[20]) Korenman, a Jewish pediatrician from Odessa, Ukraine, who was an Iranian citizen.[21][22][23][24] The Soviet government at this time courted foreign correspondents, and the family lived well while in Baku.[25] Zadeh attended elementary school for three years there,[25] which he said "had a significant and long-lasting influence on my thinking and my way of looking at things."[26]

Iran

In 1931, when Stalin began agricultural collectivization,[20] and Zadeh was ten, his father moved his family back to Tehran, Iran. Zadeh was enrolled in Alborz High School, a missionary school,[20] where he was educated for the next eight years, and where he met his future wife,[25] Fay (Faina[20]) Zadeh, who said that he was "deeply influenced" by the "extremely decent, fine, honest and helpful" Presbyterian missionaries from the United States who ran the college. "To me they represented the best that you could find in the United States – people from the Midwest with strong roots. They were really 'Good Samaritans' – willing to give of themselves for the benefit of others. So this kind of attitude influenced me deeply. It also instilled in me a deep desire to live in the United States."[26] During this time, Zadeh was awarded several patents.[25]

Zadeh sat for the Iran national university exams and placed third in the nation.[25] As a student, he ranked first in his class in his first two years. In 1942, he graduated from the University of Tehran with a degree in electrical engineering, one of only three students in that field to graduate that year, due to the turmoil created by World War II, when the United States, Britain and the Soviet Union invaded Iran. Over 30,000 American soldiers were based there, and Zadeh worked with his father, who did business with them as a contractor for hardware and building materials.[27]

United States

In 1943, Zadeh decided to leave for the United States to continue his education.[20] He travelled to Philadelphia by way of Cairo after months of delay waiting first for the proper papers and later for the right ship to appear.[citation needed] He arrived in mid-1944, lived in New York and worked for an electronic association,[20] and entered the Massachusetts Institute of Technology (MIT) as a graduate student in September that year.[27][20] While in the United States, he shortened his family name, creating a new middle name from the part he removed, and was thenceforth known as Lotfi Aliasker Zadeh.[19] He received an MS degree in electrical engineering from MIT in 1946.

In 1947, as his parents had settled in New York City, Zadeh went to work as an engineer at Columbia University.[20] Zadeh then applied to Columbia University.[27][20] Columbia admitted him as a doctoral student and offered him an instructorship as well.[27] He received his PhD in electrical engineering from Columbia in 1949 and became an assistant professor the next year.[24][27] Zadeh taught for ten years at Columbia and was promoted to full professor in 1957.

The chairman of the electronic engineering department at the University of California, wrote and offered him work.[20] In 1959, Zadeh joined the Electrical Engineering faculty at the University of California, Berkeley. During his lengthy research career, Zadeh made important scientific contributions in two distinct areas: (1) linear system theory and classical control systems, and (2) fuzzy sets, fuzzy logic, and related science and technology.

Zadeh was awarded a Guggenheim Fellowship in 1967 for Natural Sciences in Applied Mathematics.[28]

Zadeh's first important research contribution, well known among scholars of his generation in the electrical engineering community, was in the area of classical control systems. His pioneer work, co-authored with Charles Desoer, Linear System Theory: The State Space Approach, laid a critical foundation for all modern approaches to system analysis and control.[29] The second and more well-known contribution of Zadeh's research is his lifelong dedication to the creation, enhancement and the real-world impacts of a broad collection of science and technology based on fuzzy sets and fuzzy logic. He published his seminal work on fuzzy sets in 1965, in which he described the motivation of replicating human-like reasoning and detailed the mathematics of fuzzy set theory.

In 1973 he proposed his theory of fuzzy logic. Together, fuzzy sets and fuzzy logic provide the necessary foundations for a broad class of related innovations, including (but not limited to):

  • fuzzy control – a practical approach to non-linear control using fuzzy if-then rules in fuzzy logic
  • fuzzy pattern recognition – a generalization of conventional pattern recognition techniques using fuzzy sets (e.g., fuzzy k-means generalizes k-means clustering)
  • fuzzy database – generalizes classical database query language using fuzzy sets and fuzzy logic
  • fuzzy mathematics – generalizes conventional mathematics using fuzzy sets and fuzzy logic
  • neuro-fuzzy systems – a synergistic combination of fuzzy logic and neural networks, providing the first interpretable AI system based on neural network learning

He was also on the Board of Governors for International Neural Network Society (INNIS) in 2003.

Impacts to higher education

Zadeh became the Chair of Department of Electrical Engineering at the University of California, Berkeley, in 1963. One of the lasting impacts of his leadership in this role is the expansion and the integration of computer science. He initiated and completed (in 1968) the transformation of the Electrical Engineering department at UC Berkeley to the Department of Electrical Engineering and Computer Science (EECS). This strategic move not only led UC Berkeley's advancement into the top ranks of computer science education and research, but also led other research universities globally to add computer science to their electrical engineering departments. In 1973, Lotfi Zadeh received the prestigious (Institute of Electronic and Electrical Engineers) IEEE Education Award, largely in recognition of his performance as chair of EE and then EECS. Other important services to UC Berkeley include his Academic Senate committee memberships: Academic Planning & Resource Allocation (1992–95); Committees (1969–70; 1980–81); Courses of Instruction (1975–80); and Faculty Awards (1990–92). Professor Zadeh graduated more than 50 PhD students, many of whom went on to become leaders in various areas of engineering, management and information sciences.[30]

Zadeh photographed people around him.[31]

Zadeh was called "quick to shrug off nationalism, insisting there are much deeper issues in life", and was quoted as saying in an interview: "The question really isn't whether I'm American, Russian, Iranian, Azerbaijani, or anything else. I've been shaped by all these people and cultures, and I feel quite comfortable among all of them."[33] He noted in the same interview: "Obstinacy and tenacity, not being afraid to get embroiled in controversy – that's very much a Turkish tradition. That's part of my character, too. I can be very stubborn. That has probably been beneficial for the development of fuzzy logic."[34] He described himself as "an American, mathematically oriented, electrical engineer of Iranian descent, born in Russia."[24]

He and his wife Fay Zadeh had two children, Stella and Norman Zada. His wife wrote a book, My Life and Travels with the Father of Fuzzy Logic[35] about their travels and experiences together, visiting "exotic places" and meeting interesting people around the world.

Zadeh died in his home in Berkeley, California,[3] on 6 September 2017, at the age of 96.[1][2][unreliable source?] He was buried at the First Alley of Honors, on 29 September 2017[36] in Baku, Azerbaijan, the city in which he was born.[3] His funeral was well attended by "highly respected people."[37] A month prior to his death, the University of Tehran had released an erroneous report that Zadeh had died, but withdrew it several days later.[citation needed]

According to Google Scholar, as of November 2021, Zadeh's work has been cited at least 269,091 times in scholarly works,[38] with the 1965 Fuzzy sets paper receiving at least 122,743 citations.[39]

Fuzzy sets and systems

Zadeh, in his theory of fuzzy sets, proposed using a membership function (with a range covering the interval [0,1]) operating on the domain of all possible values. He proposed new operations for the calculus of logic and showed that fuzzy logic was a generalisation of classical and Boolean logic. He also proposed fuzzy numbers as a special case of fuzzy sets, as well as the corresponding rules for consistent mathematical operations (fuzzy arithmetic).[40]

Fuzzy logic and artificial intelligence

Zadeh's research career has had a lasting impact on artificial intelligence (AI). Fuzzy sets and fuzzy logic are both motivated by our understanding of human cognition: that we are comfortable with concepts that have vague boundaries. This is well aligned with the Physical symbol system assumption in AI (by Allen Newell and Herbert A. Simon), inspired by another aspect of human cognition: that humans are comfortable with concepts that are described by symbols.

The concept of a linguistic variable in fuzzy logic connects a symbol that is typically a predicate in classical logic (e.g., "John is Bold", or in predicate logic – Bold(John)) – to linguistic values (e.g., "John is somewhat bold." or in fuzzy logic – Bold(John)=Somewhat ) – which generalizes the binary value of predicate logic in two ways. First, the two possible values (True or False) in predicate logic are generalized to a continuum (typically from 0, which corresponds to False, to 1, which corresponds to True). This allows the expression of Bold(John)= 0.5, which indicates that John is midway between being devoid of boldness and being entirely bold.

The second generalization enabled by fuzzy logic is to use a fuzzy set such as "somewhat bold" to describe a person's boldness level in a way that is more natural to human understanding and communication. Without this generalization, we can only describe the value of a person's boldness as a number (e.g., 0.5) or as an interval (e.g., [0.25, 0.75]). With this generalization, one can express the semantic meaning of "somewhat bold" as a fuzzy set in the domain of 0 and 1.

Zadeh was also an active contributor to the AI community, including at the Dartmouth Workshop that coined the term "artificial intelligence". He was subsequently a frequent contributor to leading AI conferences such as AAAI and IJCAI, as well as other top venues such as AI Magazine.

Other contributions

Zadeh is credited, along with John R. Ragazzini, in 1952, with having pioneered the development of the Z-transform method in discrete time signal processing and analysis. These methods are now standard in digital signal processing, digital control, and other discrete-time systems used in industry and research. He was an editor of the International Journal of Computational Cognition.

Zadeh's work also included computing with words and perceptions. His later papers include "From Search Engines to Question-Answering Systems"[41] and "Toward a Generalized Theory of Uncertainty (GTU)—An Outline".[42]

19 His father was Rahim Aleskerzade an Iranian Muslim Azerbaijani journalist from Ardabil on assignment from Iran citation needed and his mother was Fanya Feyga 20 Korenman a Jewish pediatrician from Odessa Ukraine who was an Iranian citizen 21 22 23 24 The Soviet government at this time courted foreign correspondents and the family lived well while in Baku 25 Zadeh attended elementary school for three years there 25 which he said had a significant and long lasting influence on my thinking and my way of looking at things 26 Iran Edit In 1931 when Stalin began agricultural collectivization 20 and Zadeh was ten his father moved his family back to Tehran Iran Zadeh was enrolled in Alborz High School a missionary school 20 where he was educated for the next eight years and where he met his future wife 25 Fay Faina 20 Zadeh who said that he was deeply influenced by the extremely decent fine honest and helpful Presbyterian missionaries from the United States who ran the college To me they represented the best that you could find in the United States people from the Midwest with strong roots They were really Good Samaritans willing to give of themselves for the benefit of others So this kind of attitude influenced me deeply It also instilled in me a deep desire to live in the United States 26 During this time Zadeh was awarded several patents 25 Zadeh sat for the Iran national university exams and placed third in the nation 25 As a student he ranked first in his class in his first two years In 1942 he graduated from the University of Tehran with a degree in electrical engineering one of only three students in that field to graduate that year due to the turmoil created by World War II when the United States Britain and the Soviet Union invaded Iran Over 30 000 American soldiers were based there and Zadeh worked with his father who did business with them as a contractor for hardware and building materials 27 United States Edit In 1943 Zadeh decided to leave for the United States to continue his education 20 He travelled to Philadelphia by way of Cairo after months of delay waiting first for the proper papers and later for the right ship to appear citation needed He arrived in mid 1944 lived in New York and worked for an electronic association 20 and entered the Massachusetts Institute of Technology MIT as a graduate student in September that year 27 20 While in the United States he shortened his family name creating a new middle name from the part he removed and was thenceforth known as Lotfi Aliasker Zadeh 19 He received an MS degree in electrical engineering from MIT in 1946 In 1947 as his parents had settled in New York City Zadeh went to work as an engineer at Columbia University 20 Zadeh then applied to Columbia University 27 20 Columbia admitted him as a doctoral student and offered him an instructorship as well 27 He received his PhD in electrical engineering from Columbia in 1949 and became an assistant professor the next year 24 27 Zadeh taught for ten years at Columbia and was promoted to full professor in 1957 The chairman of the electronic engineering department at the University of California wrote and offered him work 20 In 1959 Zadeh joined the Electrical Engineering faculty at the University of California Berkeley During his lengthy research career Zadeh made important scientific contributions in two distinct areas 1 linear system theory and classical control systems and 2 fuzzy sets fuzzy logic and related science and technology Zadeh was awarded a Guggenheim Fellowship in 1967 for Natural Sciences in Applied Mathematics 28 Zadeh s first important research contribution well known among scholars of his generation in the electrical engineering community was in the area of classical control systems His pioneer work co authored with Charles Desoer Linear System Theory The State Space Approach laid a critical foundation for all modern approaches to system analysis and control 29 The second and more well known contribution of Zadeh s research is his lifelong dedication to the creation enhancement and the real world impacts of a broad collection of science and technology based on fuzzy sets and fuzzy logic He published his seminal work on fuzzy sets in 1965 in which he described the motivation of replicating human like reasoning and detailed the mathematics of fuzzy set theory In 1973 he proposed his theory of fuzzy logic Together fuzzy sets and fuzzy logic provide the necessary foundations for a broad class of related innovations including but not limited to fuzzy control a practical approach to non linear control using fuzzy if then rules in fuzzy logic fuzzy pattern recognition a generalization of conventional pattern recognition techniques using fuzzy sets e g fuzzy k means generalizes k means clustering fuzzy database generalizes classical database query language using fuzzy sets and fuzzy logic fuzzy mathematics generalizes conventional mathematics using fuzzy sets and fuzzy logic neuro fuzzy systems a synergistic combination of fuzzy logic and neural networks providing the first interpretable AI system based on neural network learningHe was also on the Board of Governors for International Neural Network Society INNIS in 2003 Impacts to higher education EditZadeh became the Chair of Department of Electrical Engineering at the University of California Berkeley in 1963 One of the lasting impacts of his leadership in this role is the expansion and the integration of computer science He initiated and completed in 1968 the transformation of the Electrical Engineering department at UC Berkeley to the Department of Electrical Engineering and Computer Science EECS This strategic move not only led UC Berkeley s advancement into the top ranks of computer science education and research but also led other research universities globally to add computer science to their electrical engineering departments In 1973 Lotfi Zadeh received the prestigious Institute of Electronic and Electrical Engineers IEEE Education Award largely in recognition of his performance as chair of EE and then EECS Other important services to UC Berkeley include his Academic Senate committee memberships Academic Planning amp Resource Allocation 1992 95 Committees 1969 70 1980 81 Courses of Instruction 1975 80 and Faculty Awards 1990 92 Professor Zadeh graduated more than 50 PhD students many of whom went on to become leaders in various areas of engineering management and information sciences 30 Personal life and beliefs EditPhotographs Zadeh at his

people around him 31 Zadeh was called quick to shrug off nationalism insisting there are much deeper issues in life and was quoted as saying in an interview The question really isn t whether I m American Russian Iranian Azerbaijani or anything else I ve been shaped by all these people and cultures and I feel quite comfortable among all of them 33 He noted in the same interview Obstinacy and tenacity not being afraid to get embroiled in controversy that s very much a Turkish tradition That s part of my character too I can be very stubborn That has probably been beneficial for the development of fuzzy logic 34 He described himself as an American mathematically oriented electrical engineer of Iranian descent born in Russia 24 He and his wife Fay Zadeh had two children Stella and Norman Zada His wife wrote a book My Life and Travels with the Father of Fuzzy Logic 35 about their travels and experiences together visiting exotic places and meeting interesting people around the world Zadeh died in his home in Berkeley California 3 on 6 September 2017 at the age of 96 1 2 unreliable source He was buried at the First Alley of Honors on 29 September 2017 36 in Baku Azerbaijan the city in which he was born 3 His funeral was well attended by highly respected people 37 A month prior to his death the University of Tehran had released an erroneous report that Zadeh had died but withdrew it several days later citation needed Work Edit Stamp of Azerbaijan dedicated to the 100th anniversary of Lotfi A Zadeh According to Google Scholar as of November 2021 Zadeh s work has been cited at least 269 091 times in scholarly works 38 with the 1965 Fuzzy sets paper receiving at least 122 743 citations 39 Fuzzy sets and systems Edit Zadeh in his theory of fuzzy sets proposed using a membership function with a range covering the interval 0 1 operating on the domain of all possible values He proposed new operations for the calculus of logic and showed that fuzzy logic was a generalisation of classical and Boolean logic He also proposed fuzzy numbers as a special case of fuzzy sets as well as the corresponding rules for consistent mathematical operations fuzzy arithmetic 40 Fuzzy logic and artificial intelligence Edit Zadeh s research career has had a lasting impact on artificial intelligence AI Fuzzy sets and fuzzy logic are both motivated by our understanding of human cognition that we are comfortable with concepts that have vague boundaries This is well aligned with the Physical symbol system assumption in AI by Allen Newell and Herbert A Simon inspired by another aspect of human cognition that humans are comfortable with concepts that are described by symbols The concept of a linguistic variable in fuzzy logic connects a symbol that is typically a predicate in classical logic e g John is Bold or in predicate logic Bold John to linguistic values e g John is somewhat bold or in fuzzy logic Bold John Somewhat which generalizes the binary value of predicate logic in two ways First the two possible values True or False in predicate logic are generalized to a continuum typically from 0 which corresponds to False to 1 which corresponds to True This allows the expression of Bold John 0 5 which indicates that John is midway between being devoid of boldness and being entirely bold The second generalization enabled by fuzzy logic is to use a fuzzy set such as somewhat bold to describe a person s boldness level in a way that is more natural to human understanding and communication Without this generalization we can only describe the value of a person s boldness as a number e g 0 5 or as an interval e g 0 25 0 75 With this generalization one can express the semantic meaning of somewhat bold as a fuzzy set in the domain of 0 and 1 Zadeh was also an active contributor to the AI community including at the Dartmouth Workshop that coined the term artificial intelligence He was subsequently a frequent contributor to leading AI conferences such as AAAI and IJCAI as well as other top venues such as AI Magazine Other contributions Edit Zadeh is credited along with John R Ragazzini in 1952 with having pioneered the development of the Z transform method in discrete time signal processing and analysis These methods are now standard in digital signal processing digital control and other discrete time systems used in industry and research He was an editor of the International Journal of Computational Cognition Zadeh s work also included computing with words and perceptions His later papers include From Search Engines to Question Answering Systems 41 and Toward a Generalized Theory of Uncertainty GTU An Outline 42 Selected publications EditA complete list of publications is available 43 June 1965 Fuzzy sets
