‘Probably Approximately Correct’ Inventor, From Harvard U., Wins Turing Award

An artificial-intelligence pioneer has won the A.M Turing Award, the Association for Computing Machinery announced today. Leslie G. Valiant, a professor of computer science and applied mathematics at Harvard University, won $250,000 with the prestigious award, named after British mathematician Alan Turing. Mr. Valiant was cited for his work on computational learning theory, including a method called “Probably Approximately Correct,” which, despite its name, is an exacting way to analyze how a machine learns. He also contributed fundamental insights into parallel computing, which has become a standard way to increase machine calculation power, and ventured into neuroscience with a proposal for a mathematical model of the mind.
