Google Doodle honors Lotfi Zadeh, the father of fuzzy logic

Google

In 1964, while considering how to program software for handwriting recognition, mathematician, computer scientist, and electrician Lotfi Zadeh devised a new mathematical method. His fuzzy logic theory offered a rigorous yes-no logic alternative in an attempt to imitate how people see the world.

Fuzzy logic will eventually be equally accepted by academia and industry, contributing to medicine, economic modeling, and consumer products such as anti-lock brakes, dishwashers, and elevators, to name just a few. To celebrate his controversial innovation, Google dedicated Doodle to Zadeh on Tuesday to celebrate the 57th anniversary of the creation of the concept.

Doodle illustrates his notion and presents an alternative to black or white binary logic that determines membership for a particular class based on 1 (yes) or 0 (no). His theory provided a means to calculate the median between yes and no.

Zade was born on February 4, 1921 in Azerbaijan to a doctor’s mother and a journalist’s father. At the age of 10, his family moved to Iran, where he graduated with a bachelor’s degree in science from the University of Tehran. He earned enough money to sell goods to the U.S. military during World War II and moved to continue his education in the United States, earning a master’s degree in electrical engineering from the Massachusetts Institute of Technology in 1946. I got a PhD. From Colombia in 1949.

While serving as a professor of electrical engineering at the University of California, Berkeley, Zadeh suggested using inaccurate data to solve problems that could have multiple solutions. His 1965 paper, Fuzzy Sets-Information and Control, uses mathematics to define human concepts such as “slightly,” “tall,” and “beautiful,” as well as other ambiguous concepts. It was made. membership.

Zadeh’s theory was controversial, and much of academia ridiculed and attacked it. This is mainly due to the challenge of other, more widely accepted forms of mathematics and the use of unusual terms.

“My dissertation was the subject of indifference, skepticism, and ridicule,” he wrote in 2015.

“In part, many negative reactions to my dissertation reflect the fact that the word” fuzzy “has a derogatory meaning,” he wrote.

Despite criticism, Zade has received dozens of engineering and academic awards for his work, including 24 honorary doctorates.

Zade died in 2017 at the age of 96.
