Zadeh refers to Lotfi Zadeh, an influential mathematician and computer scientist known for founding the field of fuzzy logic. Born in 1921 in Azerbaijan, he later moved to the United States, where he developed theories that allow for reasoning with uncertain or imprecise information. His work has applications in various fields, including artificial intelligence, control systems, and decision-making. Fuzzy logic, introduced by Zadeh in 1965, extends traditional binary logic by incorporating degrees of truth rather than just true or false values. This approach enables more flexible and human-like reasoning, making it useful in areas such as automated systems, data analysis, and machine learning.
