Lotfi A. Zadeh Biography

Due to his extraordinary studies he wanted to study higher education, so went to the U.S. to attend the Massachusetts Institute of Technology (MIT) for doing graduation. He got his doctorate in electrical engineering degree in 1949 and later he went to New York and taught systems theory at Columbia University in New York.

And later in 1959, he became a professor at the University of California, Berkeley, Which later registered as his academic home in his lifelong career. It was the place where he innovated the fuzzy breakthrough.

The world knows him as a mathematician, electrical engineer, artificial intelligence researcher, computer scientist, and professor emeritus of computer science at the University of California, Berkeley.

He published his Fuzzy Sets on 30 Nov. 1965, which has since been cited by scholars nearly 100,000 times. His theory gave an alternative to the rigid “black and white” parameters of traditional logic and instead allowed for more ambiguous or “fuzzy” boundaries that more closely mimic the way humans see the world.

His concepts have been used in various technological works to date, from a Japanese subway system to the anti-skid algorithms that keep cars safe on the road. 

Zadeh became worldwide popular when he gave fuzzy mathematics to the world that has many fuzzy related concepts included like fuzzy sets, fuzzy semantics, fuzzy languages, fuzzy logic, fuzzy algorithms, fuzzy control, fuzzy events, fuzzy systems, fuzzy probabilities, and fuzzy information. 

Zadeh was also the founding member of the Eurasian Academy.

He received countless awards and prizes all through his career including an honorary professorship from the government of Azerbaijan in 1993. I will mention all the popular awards below in this post.

Today on 30 Nov 2021 Google Doodle also honored him, as on 30 Nov.1964 Zadeh submitted his Fuzzy Sets,” a groundbreaking paper that told the world to his new innovative mathematical framework called “fuzzy logic.”

Lotfi A. Zadeh Early life and education

Lotfi A. Zadeh is born in  Baku, Azerbaijan SSR on February 4, 1921.  Zadeh was brought into the world in Baku, Azerbaijan SSR, as Lotfi Aliaskerzadeh, to Rahim Aleskerzade, an Iranian Azerbaijani writer from Ardabil on task from Iran, and Fanya Korenman, a Russian Jewish pediatrician from Odessa and an Iranian resident.

Lotfi A. Zadeh Early life and education

The Soviet government right now pursued unfamiliar reporters, and the family lived well while in Baku. Zadeh went to grade school for quite some time there, which he said: "affected my reasoning and my perspective on." 

In 1931, when Zadeh was ten years of age, his family moved to Tehran in Iran, his dad's country. Zadeh was taken a crack at Alborz College, which was a Presbyterian preacher school, where he was taught for the following eight years, and where he met his future spouse, Fay.

Zadeh says that he was "profoundly impacted" by the "amazingly fair, fine, genuine and accommodating" evangelists from the United States who ran the school. "To me, they addressed all that you could find in the United States – individuals from the Midwest with solid roots.

They were 'Great Samaritans' – ready to give of themselves to serve others. So this sort of mentality impacted me profoundly. It additionally ingrained in me a profound longing to live in the United States." During this time, Zadeh was granted a few licenses. 

In spite of being more familiar with Russian than in Persian, Zadeh sat for the public college tests and set third in the whole country.

As an understudy, he positioned first in quite a while class in his initial two years. In 1942, he moved on from the University of Tehran with a degree in electrical designing, one of just three understudies in that field to graduate that year, because of the disturbance made by World War II, when the United States, Britain, and the Soviet Union attacked Iran.

More than 30,000 American fighters were based there, and Zadeh worked with his dad, who worked with them as a worker for hire for equipment and building materials. 

In 1943, Zadeh chose to emigrate to the United States and went to Philadelphia via Cairo following quite a while of defer sitting tight for the appropriate papers or for the right boat to show up. He showed up in mid-1944 and entered the Massachusetts Institute of Technology (MIT) as an alumni understudy soon thereafter. While in the United States, he changed his name to Lotfi Aliasker Zadeh. 

He got an MS degree in electrical designing from MIT in 1946, and afterward applied to Columbia University, as his folks had gotten comfortable in New York City. Columbia conceded him as a doctoral understudy and offered him an instructorship also.

He accepted his Ph.D. in electrical design from Columbia in 1949 and turned into an associate teacher the following year. 

Zadeh educated for a considerable length of time at Columbia was elevated to Full Professor in 1957. In 1959, Zadeh joined the staff of the Department of Electrical Engineering at the University of California, Berkeley.

For the duration of his long-lasting exploration profession, Zadeh has made two significant, yet rather particular, logical commitments: (1) straight framework hypothesis and old-style control frameworks, and (2) fluffy sets, fluffy rationale, and related science and innovation. 

Zadeh's first significant exploration commitment, notable among researchers of his age in the Electrical Engineering people group, is really in the space of traditional control frameworks. His pioneer work, co-composed with Charles Desoer, ''Linear System Theory: The State Space Approach" established a basic framework for all advanced ways to deal with framework examination and control. 

The second, and the most notable, commitment of Zadeh's exploration is his deep-rooted devotion to the creation, improvement, and this present reality effects of a wide assortment of science and innovation that depends on fluffy sets and fluffy rationale. 

He distributed his fundamental work on fluffy sets in 1965, in which he depicted the inspiration (human-like thinking) and nitty-gritty the math of the fluffy set hypothesis. In 1973 he proposed his hypothesis of fluffy rationale. Together, fluffy sets and fluffy rationale, give the fundamental establishments to an expansive class of related developments, including (yet not restricted to) the accompanying:

  • fuzzy pattern recognition: generalizes conventional pattern recognition techniques using fuzzy sets (e.g., fuzzy k-means generalizes k-means clustering)
  • fuzzy control: a practical approach to non-linear control using fuzzy if-then rules in 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.
  • fuzzy mathematics: generalizes conventional mathematics using fuzzy sets and fuzzy logic.
  • fuzzy database: generalizes the classical database query language using fuzzy sets and fuzzy logic.

Role of his Higher studies on his Career

Zadeh turned into the Chair of the Department of Electrical Engineering at the University of California, Berkeley in 1963. One of the enduring effects of his authority in this job is the extension and the combination of software engineering.

He started and finished (in 1968) the change of Department of Electrical Engineering (EE) at UC Berkeley to Department of Electrical Engineering and Computer Science (EECS). This essential move not just began the progression of UC Berkeley into the highest levels of software engineering instruction and exploration, yet additionally started a worldwide development among Research I colleges that large numbers of them changed EE Department into EECS during that period.

In 1973, Lotfi Zadeh got the renowned (Institute of Electronics and Electrical Engineers) IEEE Education Award, to a great extent in acknowledgment of his presentation as the seat of EE and afterward EECS. Other significant administrations to UC Berkeley incorporate his Academic Senate board enrollments: Academic Planning and Resource Allocation (1992-95); Committees (1969-70; 1980-81); Courses of Instruction (1975-80); and Faculty Awards (1990-92).

Educator Zadeh graduated in excess of 50 Ph.D. understudies, a significant number of whom proceeded to become pioneers across numerous spaces of designing, the board, and the data sciences.

Personal life, Family details, and beliefs

Every person is built by his personal belief and mindset and that is true for Zadeh too. Here I will share some details about his personal life and beliefs below.

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.

Personal life, Family details, and beliefs

I've been shaped by all these people and cultures and I feel quite comfortable among all of them." 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's probably been beneficial for the development of Fuzzy Logic." He described himself as "an American, mathematically oriented, electrical engineer of Iranian descent, born in Russia."

Zadeh was married to Fay Zadeh and had two children, Stella Zadeh and Norman Zada. Zadeh's wife, Fay Zadeh, wrote about her travels and their experiences together in visiting "exotic places" and meeting interesting people around the world in her book -- My Life and Travels with the Father of Fuzzy Logic.

Zadeh died in his home in Berkeley, California, on September 6, 2017, at the age of 96. He is buried in the first Alley of Honor in Baku, Azerbaijan, the city in which he was born. His funeral was well attended by "highly respected people", including the President of Azerbaijan, Ilham Aliyev. A month previous to his death, the University of Tehran had released an erroneous report that Zadeh had died, but withdrew it several days later.

Lotfi A. Zadeh salary and net worth

There are a lot of people who are interested to know about the net worth of Lotfi A. Zadeh but they don't get any update about his net worth and monthly salary.

But as you may know that Zedeh is not more now in this world so his salary and net worth can't be told. Today we can say his net worth is all the work that he did, which helped us to build better technology.

Lotfi Zadeh Works

Let's check his main works which he did all through his lifelong career.

Fuzzy sets and systems

Zadeh, in his hypothesis of fluffy sets, proposed utilizing a participation work (with a reach covering the stretch [0,1]) working on the space of every conceivable worth. He proposed new activities for the math of rationale and showed that fluffy rationale was speculation of traditional and Boolean rationale.

He additionally proposed fluffy numbers as an exceptional instance of fluffy sets, just as the comparing rules for predictable numerical tasks (fluffy math).

Fuzzy Logic and Artificial Intelligence

Zadeh's exploration profession lastingly affects man-made reasoning (AI). Fluffy sets and fluffy rationale are both inspired by human cognizance that shows we are OK with ideas that have unclear limits.

This is very much lined up with the Physical image framework suspicion in AI (by Allen Newall and Herbert A. Simon), which is likewise enlivened by the human perception that demonstrates we (humans) are alright with ideas that are portrayed by images.

The idea of semantic variable in fluffy rationale associates an image that is ordinarily a predicate in old-style rationale (e.g., "John is Bold", or in predicate rationale Bold(John)) to etymological qualities (e.g., "John is to some degree striking." or in fluffy rationale Bold(John)=Somewhat ), which sums up the double worth of predicate rationale in two ways.

To begin with, the two potential qualities (True or False) in predicate rationale are summed up to a continuum (normally from 0, which compares to False, to 1, which relates to True). This permits the outflow of Bold(John)= 0.5, which shows John is between totally not intense and not totally strong. The subsequent speculation empowered by fluffy rationale is to utilize fluffy sets, for example, "fairly strong" to portray an individual's strength level in a manner that is more normal to human arrangement and correspondence.

Without this speculation, we can just depict the worth of an individual's intensity as a number (e.g., 0.5) or as a span (e.g., [0.25, 0.75]). With this speculation, one can communicate the semantics (which means) of "fairly striking" as a fluffy set in the space of 0 and 1. 

Zadeh has additionally been a functioning supporter of the AI people group. He is one of the participants of the Dartmouth Workshop that begat the expression "man-made reasoning". From that point forward, he is a regular supporter of driving AI gatherings, for example, AAAI, IJCAI just as other top settings like AI Magazine.

Other works

Zadeh is likewise acknowledged, alongside John R. Ragazzini, in 1952, with having spearheaded the improvement of the Z-change strategy in discrete-time signal handling and examination. These techniques are currently standard in advanced sign handling, computerized control, and other discrete-time frameworks utilized in industry and exploration. He was a proofreader of the International Journal of Computational Cognition. 

Zadeh's latest work included figuring with words and discernments. His new papers incorporate From Search Engines to Question-Answering Systems—The Role of Fuzzy Logic, Progress in Informatics, No. 1, 1–3, 2005; and Toward a Generalized Theory of Uncertainty (GTU)— An Outline, Information Sciences, Elsevier, Vol. 172, 1–40, 2005.
