    Three space-oriented projects at CMU's Robotics Institute are described: the Ambler planetary rover, the self-mobile space manipulator and the Hubble space telescope scheduling system. The Ambler planetary rover project is a comprehensive research program to design and build an intelligent machine that will explore and sample extraterrestrial planetary surfaces. The self-mobile space manipulator r... View full abstract»

    A brief history of planning research done by the group that produced the RMS (remote mission specialist) planner is presented. Space telerobotics under study at JPL is then discussed, and RMS is described in detail. How RMS functions in an example execution is examined. The planner's capabilities are summarized, and possible future applications are suggested.<> View full abstract»

    Representation selection for a constraint satisfaction problem (CSP) is addressed. The CSP problem class is introduced and the classic n-queens problem is used to show that many different CSP representations may exist for a given real-world problem. The complexities of solving these alternative representations are compared empirically and theoretically. The good agreement found is due to two key f... View full abstract»

    The development of five expert systems of varying complexity is described. The five expert systems are: FAST, a system for the performance tuning of a large software system; Maven, a system for assigning Bellcore's Common Language equipment codes; GADS, a diagnostic shell for constructing hot-line support applications; Bellcore's OS-Assist system, a support tool for managers in directory-assistanc...

  • Capturing knowledge through top-down induction of decision trees

    TDIDT (top-down induction of decision trees) methods for heuristic rule generation lead to unnecessarily complex representations of induced knowledge and are overly sensitive to noise in training data. Practical alternatives to TDIDT approaches which lead to more direct representations of the same knowledge, are examined. The alternatives are more immune to problems with spurious correlations in s... View full abstract»

    D.E. O'Leary (1987) noted the inappropriate nature of traditional software validation techniques for expert system validation and proposed a research methods approach. R.M. O'Keefe et al. (1987) established validation as an important concern in expert system research and development and presented general descriptive methodologies for qualitative and quantitative methods of formal validation. A spe... View full abstract»

    Computer risk exposures and security in general are reviewed, and factors suggesting that expert system security is a unique problem are examined. Security requirements associated with the unique characteristics of expert systems are investigated. They include technical aspects of knowledge (certainty factors, symbolic information and special fixes), structure (user interface, knowledge base, infe... View full abstract»

    The production of understandable and maintainable expert systems using the current generation of multiparadigm development tools is addressed. This issue is discussed in the context of COMPASS, a large and complex expert system that helps maintain an electronic telephone exchange. As part of the work on COMPASS, several techniques to aid maintainability were developed and successfully implemented.... View full abstract»
