In 1921 Lotfi Zadeh was born in Baku, the capital of the former Soviet Republic of Azerbaijan, where his Iranian father worked as a journalist.

When he was 10 years old, his family moved to Tehran, Iran, and Lotfi was sent to an American Presbyterian missionary school.

Due to an administrative oversight, he enrolled in a class many years before his supposed academic level, but that didn’t stop him from excelling in his studies, and his university entrance exam was the third highest in the entire country.

Lotfi Zadeh Education

Lotfi Zadeh graduated from the University of Tehran in 1942 as an electrical engineer, one of only three students involved in World War II disruption. In 1943, he moved to the United States, where he earned a Masters in Electrical Engineering from the Massachusetts Institute of Technology (MIT).

Then 6 Years later, Lotfi Zadeh earned his PhD at Columbia University (New York) on the same subject, where he will teach for the next 10 years.

In 1959, Lotfi Zadeh joined the Department of Electrical Engineering and Computer Science at the University of California, Berkeley, where he has led the Berkeley Initiative in Soft Computing since 1991.

Lotfi Zadeh published his seminal work on the fuzzy set in 1965, and in 1968 proposed the theory of his fuzzy logic.

More than two decades later, in 1991, he introduced another new paradigm: soft computing, a hybrid method of embracing fuzzy logic, a neural network, evolutionary algorithms, and probabilistic reasoning.

According to Google Scholar, the author of 245 papers, his research has been viewed more than 90,000 times, and the vitality and impact of the field he created has been proven by the number of papers – about 253,000 – including the word ‘fuzzy’. Their numbers.

Lotfi Zadeh was the editor-in-chief of 75 expert journals, and although the fuzzy set and logic generated thousands of patents, not a single one was in his name.

About Lotfi Zadeh

The theory of “fuzzy sets” is a mathematical theory of modern algebra. It was presented by Lotfi Zadeh in 1965. This theory is the basis of another new mathematical concept called “fuzzy logic”, also developed by Lotfi Zadeh.

The goal of fuzzy logic is to theoretically model the representation of human knowledge. On a practical level, fuzzy subset theory and fuzzy logic are used to improve decision systems.

By “decision system” we mean devices and tools that work with a form of artificial intelligence. These tools and software must be able to answer questions, because they know the “facts”, they know the “rules”, and become able to perform “reasoning” from known facts and rules to produce new “facts. ”Thanks to a“ reasoning engine ”. 

In this process, the study of fuzzy subsets is essential, because it allows to model two things: to present “a model of uncertainties and imprecisions”, but also “to model precise information” in the form of a “language”. mathematics comparable to that used today in tools that serve as decision support.

Lotfi Zadeh’s subset theory, a basis of his fuzzy logic, is used in the theoretical field of mathematics, but it is practically used in electronic tools of artificial intelligence to different degrees and in a wide variety of fields.

Fuzzy logic is used in simple or complex automatic electronic tools, i.e. machines intended to substitute for humans in decision-making processes, for example electronic process control of ABS brakes.

Lotfi Zadeh Death

Lotfi Zadeh (real name Lotf-Ali Askarzadeh) died on September 6, 2017 in Berkeley, California at the age of 96. Computer scientist and electrical engineer whose theories on “fuzzy logic” have crossed academia and universities, but also the world of industry.

Lotfi Zadeh has influenced very different areas of the contemporary world, from linguistics to economics, from medicine to household appliances (air conditioners, vacuum cleaners and rice cookers), etc.
