Research on Grey-Rough Set Model and Its Application in Data Mining [PDF]
, 2005 粗糙集理论和灰色系统理论都是处理不完全、不精确及不确定信息的有效工具，通过对这两种理论进行结合和互补来研究处理不确定性问题的更有效和更一般化的方法，特别是数据挖掘方法，无疑是一项有现实意义的工作.本文将粗糙集理论和灰色系统理论有机地结合起来，创新性地提出灰色粗糙集的一些概念，在此基础上提出几种有价值的处理不完备信息和不确定知识的灰色粗糙集模型.本文的主要研究工作如下：(1)研究了两种处理不确定性问题的重要理论——粗糙集理论和灰色系统理论，阐述了这两种理论的基本概念及其思想内涵.(2 ...
