Zusammenfassung:Abstract: "PRODIGY is a computational architecture that integrates general problem solving and multiple learning methods. The primary design objectives are: to provide an open-architecture research vehicle to gain insight into deliberative symbolic reasoning, to investigate learning in the context of a performance engine, to permit the evaluation of multiple learning techniques within the same architecture in multiple domains, and to provide a basis for the development of flexible, adaptive knowledge-based systems. The PRODIGY system consists of a general planning and problem-solving engine, a set of machine learning techniques, and multiple knowledge sources encoded in a uniform, logic based knowledge representation
In particular, PRODIGY learns control knowledge via explanation-based learning and static domain analysis, forms abstraction hierarchies for effective planning, recycles past experience via derivational analogy, extends and refines domain knowledge through experimentation, and acquires knowledge dynamically from domain experts. PRODIGY has been tested in various domains such as basic machine-shop scheduling and high-level robotic planning. This paper focuses primarily on the general PRODIGY problem solver, the explanation-based learning method, the abstraction learning method, and an empirical evaluation of these methods on large populations of problems.
