属性集变化时覆盖信息系统的相关族属性约简
Related family-based attribute reduction of covering information systems when varying attribute sets
摘要：
在实际应用中，存在着大量的属性变化的动态覆盖信息系统，但关于动态覆盖信息系统的相关族属性约简的研究却很少。本文首先研究了相容和不相容覆盖信息系统的属性约简的更新机制。然后通过实例说明如何计算属性集变化的动态覆盖信息系统的属性约简。实验结果表明，当属性集随时间变化时，相关的基于族的方法对动态覆盖信息系统的属性约简是有效的.
英文摘要：
In practical situations, there are many dynamic covering information systems with variations of attributes, but there are few studies on related family-based attribute reduction of dynamic covering information systems. In this paper, we first investigate updated mechanisms of constructing attribute reducts for consistent and inconsistent covering information systems when varying attribute sets by using related families. Then we employ examples to illustrate how to compute attribute reducts of dynamic covering information systems with variations of attribute sets. Finally, the experimental results illustrates that the related family-based methods are effective to perform attribute reduction of dynamic covering information systems when attribute sets are varying with time.
