Title: Some Topics in Neural Networks and Control Abstract: We present a new algorithm for finding low complexity neural networks with high generalization capability. The algorithm searches for a "flat" minimum of the error function. A flat minimum is a large connected region in weight-space where the error remains a...

Title: AN ENHANCER FOR REACTIVE PLANS Abstract: This paper describes our method for improving the comprehensibility, accuracy, and generality of reactive plans. A reactive plan is a set of reactive rules. Our method involves two phases: (1) formulate explanations of execution traces, and then (2) generate new reactiv...

Title: Evolutionary Neural Networks for Value Ordering in Constraint Satisfaction Problems Abstract: Technical Report AI94-218 May 1994 Abstract A new method for developing good value-ordering strategies in constraint satisfaction search is presented. Using an evolutionary technique called SANE, in which individual n...

Title: Refining Conversational Case Libraries Abstract: Conversational case-based reasoning (CBR) shells (e.g., Inference's CBR Express) are commercially successful tools for supporting the development of help desk and related applications. In contrast to rule-based expert systems, they capture knowledge as cases rat...

Title: A Computational Account of Movement Learning and its Impact on the Speed-Accuracy Tradeoff Abstract: We present a computational model of movement skill learning. The types of skills addressed are a class of trajectory following movements involving multiple accelerations, decelerations and changes in direction ...

Title: Improving accuracy by combining rule-based and case-based reasoning Abstract: An architecture is presented for combining rule-based and case-based reasoning. The architecture is intended for domains that are understood reasonably well, but still imperfectly. It uses a set of rules, which are taken to be only a...

Title: Shattering all sets of k points in "general position" requires (k 1)=2 parameters Abstract: For classes of concepts defined by certain classes of analytic functions depending on n parameters, there are nonempty open sets of samples of length 2n + 2 which cannot be shattered. A slighly weaker result is also pro...

Title: Adapting Abstract Knowledge Abstract: For a case-based reasoner to use its knowledge flexibly, it must be equipped with a powerful case adapter. A case-based reasoner can only cope with variation in the form of the problems it is given to the extent that its cases in memory can be efficiently adapted to fit a ...
