Some of Valiant's biggest contributions concern the mathematical foundations of computer learning, an area of study that has led to breakthroughs such as IBM Corp.'s Watson, the machine built to play "Jeopardy!" In matches aired last month, the computer breezed past two of the game show's top winners in a display of how far computer scientists have come in programming computers to understand

the subtleties of human language and make decisions based on the mountains of data the machines are able to store.

The association cited contributions that have led to advances in artificial intelligence and areas such as natural language processing, handwriting recognition and computer vision.
