粗集在知识发现中的应用

Applications of Rough Set in Knowledge Discovery

粗集作为一种数据分析理论 ,能有效地从不确定性的数据中发现知识 ,是目前在知识发现领域研究的热点之一。首先对粗集理论做了简单介绍 ,在此基础上论述了粗集作为一种数学工具在知识发现领域中的重要问题 ,并提出粗集的进一步可能发展方向。

Rough set, as a theory of data analysis, can deal with uncertainty efficiently ,and is one of current hot research directions in knowledge discovery. This paper introduces rough set theory briefly. Based on this, this paper discusses some important issues of rough set as a mathematic tool in knowledge discovery. A perspective is also proposed for the development of rough set theory and its application.
