  • Local expression languages for probabilistic dependence

    Creator:
    D'Ambrosio, Bruce
    Abstract:
    A Belief Net is a factored representation for a joint probability distribution over a set of variables. This factoring is made possible by the conditional independence relationships among variables made evident in the sparseness of the graphical level of the net. There is, however, another source of factoring available which...

  • A computational model of resource-bounded reasoning and decision-making under uncertainty

    Creator:
    D'Ambrosio, Bruce
    Abstract:
    A complete approach to uncertainty management requires support for interactive and in­cremental problem formulation, inference, hypothesis ranking, and decision making. In addition, computational models must allow for time and resource bounds. Current ap­proaches to uncertainty management concentrate primarily on inference, provide little or no support for the larger issues in...

  • A hybrid approach to reasoning under uncertainty

    Creator:
    D'Ambrosio, Bruce
    Abstract:
    A complete approach to reasoning under uncertainty requires support for both identification of the appropriate hypothesis space and ranking hypotheses based on available evidence. We present a hybrid reasoning scheme which combines symbolic and numeric methods for uncertainty management to provide efficient and effective support for both of these tasks....

  • Extending the mathematics in Qualitative Process theory

    Creator:
    D'Ambrosio, Bruce
    Abstract:
    Reasoning about physical systems requites the integration of a range of knowledge and reasoning techniques. P. Hayes has named the enterprise of identifying and formalizing the common-sense knowledge people use for th.is task "naive physics." Qualitative Process theory by K. Forbus proposes a structure and some of the content of...

  • Artificial intelligence at OSU

    Creator:
    Dietterich, Thomas G. and D'Ambrosio, Bruce
    Abstract:
    This report describes of current research in Artificial Intelligence at Oregon State University. The five areas of active research are ( a) intelligent aids for me­chanical engineering design, (b) active experimentation as a method in machine learning, ( c) techniques for combining logic programming and assumption-based truth maintenance, ( d)...

  • Selecting appropriate representations for learning from examples

    Creator:
    Flann, Nicholas S. and Dietterich, Thomas G.
    Abstract:
    The task of inductive learning from examples places constraints on the representation of training instances and concepts. These constraints are different from, and often incompatible with, the constraints placed on the representation by the performance task. This incompatibility explains why previous researchers have found it so difficult to construct good...

  • The test incorporation hypothesis and the weak methods

    Creator:
    Bennett, James S. and Dietterich, Thomas G.
    Abstract:
    Test incorporations are program transformations that improve the performance of generate-and-test procedures by moving information out of the "test" and into the "generator." The test information is said to be "incorporated" into the generator so that items produced by the generator are guaranteed to satisfy the incorporated test. This article...

  • Combining opinions from several experts

    Creator:
    Ling, Xiaoning and Rudd, W. G.
    Abstract:
    This paper addresses the problem of aggregating a number of expert opinions which have been expressed in some numerical form. An important feature of sets of expert opinions is the possibility of stochastic dependence between members of the sets. We develop an approach for combining expert opinions which formally allows...
