Biography
Leslie Valiant revolutionized computer science by introducing probably approximately correct (PAC) learning, establishing the mathematical foundations for machine learning. His work bridged computational complexity theory and statistical learning, proving that certain functions could be learned efficiently from examples. A Turing Award winner, Valiant's theories underpin modern artificial intelligence and deep learning systems.
