ABDUCTION-BASED DIAGNOSIS - A COMPETITION-BASED NEURAL MODEL SIMULATING ABDUCTIVE REASONING

Diagnosis is an active research area where many diagnostic methods have been proposed. In this paper, we make explicit the features that characterize these methods within a conventional framework as well as within a neural framework. Specifically, we show that each representation of diagnostic knowledge requires a specific reasoning type whichever framework is adopted, logical or neural. Then, we propose a distributed neural model to mechanize abductive reasoning within a neural framework. Finally, we compare our work with other proposals and indicate directions deserving further investigation. (C) 1995 Academic Press, Inc.
