In plain wordsAn Indian-American computer scientist who pioneered computer speech recognition and large AI systems at Carnegie Mellon University, and shared the 1994 Turing Award.
Indian-American computer scientist at Carnegie Mellon University and a pioneer of speech recognitionspeech recognition, n.: Technology that turns spoken words into written text, as when a phone transcribes a voice message or captions appear automatically under a video. and large-scale AI systems. After a Stanford PhD (1966) on speech recognition supervised by John McCarthyJohn McCarthy, prop. n.: The American computer scientist who coined the term 'artificial intelligence', invented the Lisp programming language and championed formal logic as the route to machine common sense., he moved to Carnegie Mellon in 1969, where his group built the Hearsay systems, whose blackboard architectureblackboard system, n.: A design for AI programs that lets many independent specialist modules collaborate only through a shared workspace: each watches it, posts a piece of the answer when it sees a chance, and builds on what others posted. let independent knowledge sources cooperate on a shared hypothesis, and Harpy (1976), whose pruned search introduced beam searchbeam search, n.: A search method that keeps several of the best partial answers at each step, rather than only the single best, to find a better overall result without trying every possibility.; his students went on to create the Dragon and Sphinx recognizers. He was founding director of the Carnegie Mellon Robotics Institute (1979–1991) and dean of its School of Computer Science (1991–1999), and has long promoted computing for people in developing countries. He shared the 1994 Turing AwardTuring Award, prop. n.: Nicknamed the 'Nobel Prize of computing', the top honor in computer science, awarded each year since 1966 by the Association for Computing Machinery. Several AI pioneers have received it. with Edward FeigenbaumEdward Feigenbaum, prop. n.: An American computer scientist who pioneered expert systems, programs that capture specialists' knowledge as rules to solve problems in fields such as chemistry and medicine., honored for showing that large AI systems could be built and put to practical use, and was its first Asian-born recipient.
