基于数据挖掘技术的范例库维护

Case based maintaining with data mining

在范例推理系统中,系统的学习会使范例库无限增大,会导致系统的功能不断下降。范例推理学习系统必须有范例库的维护。本文在详细讨论了范例库的维护技术的同时,提出了一个基于数据挖掘技术的维护策略,以保证系统的学习不影响系统性能。

In case-based system, learning makes the case base expand quickly,which enable the search time becoming longer and longer.At this time,the system needs maintenance. In general, there are some methods about maintenance,for instance, utility policy,deletion policy. This paper discusses emphatically a method based on data mining policy . The experimental result shows that the method has better performance than other methods.
