Maintenance of Case Contents and Adaptation Rules

نویسنده

  • Brian Schack
چکیده

This research summary outlines and addresses three problems in casebased maintenance on case contents and adaptation rules: 1) how to perform maintenance on divisible cases with non-uniform sizes, 2) how can adaptation knowledge improve the performance of maintenance on structured cases, 3) how to determine and use coverage for adaptation rules. Evaluation showed that, for suitable cases bases, maintenance strategies that subdivide cases and employ adaptation knowledge can outperform per-case strategies. A planned experiment will expand or contract the coverage claimed by adaptation rules and measure the effects on problem-solving performance. The conclusion summarizes research progress to date and areas for further research.

A Fuzzy-Rough Approach for Case Base Maintenance

This paper proposes a fuzzy-rough method of maintaining CaseBased Reasoning (CBR) systems. The methodology is mainly based on the idea that a large case library can be transformed to a small case library together with a group of adaptation rules, which take the form of fuzzy rules generated by the rough set technique. In paper [1], we have proposed a methodology for case base maintenance which ...

Adaptation-Guided Case Base Maintenance

In case-based reasoning (CBR), problems are solved by retrieving prior cases and adapting their solutions to fit; learning occurs as new cases are stored. Controlling the growth of the case base is a fundamental problem, and research on case-base maintenance has developed methods for compacting case bases while maintaining system competence, primarily by competencebased deletion strategies assu...

Case-Based Reasoning and Adaptation in Hydraulic Production Machine Design

Case-Based Reasoning (CBR) can support hydraulic circuit design. Existing expert systems for hydraulic system design use production rules as its source of knowledge. However, this leads to problems of knowledge acquisition and knowledge base maintenance. This paper describes the application of CBR to hydraulic circuit design for production machines, which helps solving problems using past exper...
