David A. McAllester of the American Association of Artificial Intelligence since 1997. He has authored over 100 refereed publications. McAllester's research areas include machine learning theory, the theory of programming languages, automated reasoning, AI planning, computer game playing (computer chess), and computational linguistics. A 1991 paper on AI planning proved to be one of the most influential papers of the decade in that area. A 1993 paper on computer game algorithms influenced the design of the algorithms used in the Deep Blue system that defeated Garry Kasparov. A 1998 paper on machine learning theory introduced PAC-Bayesian theorems which combine Bayesian and non-Bayesian methods.
Deep Blue (chess computer) the two racks that made up Deep Blue is on display at the National Museum of American History in their exhibit about the Information Age; the other rack appears at the Computer History Museum in the "Artificial Intelligence and Robotics" gallery of the Revolution exhibit. Reports that Deep Blue was sold to United Airlines appear to originate from confusion between Deep Blue itself and other RS6000/SP2 systems. Feng-hsiung Hsu later claimed in his book "Behind Deep Blue" that he had the rights to use the Deep Blue design to build a bigger machine independently of IBM to take Kasparov's rematch
