Abstract

Abstract: The information entropy of attributes is introduccd in random information systems.The relativity between two attribute subsets is depicted by means of information entropy.A method of knowledge reduction is proposcd using information entropy and an algorithm based on this method is given.

Key words: random information systems, information entropy, relativity, knowledge reduction

摘要： 引入随机信息系统的属性的信息熵，利用属性的信息熵来刻画随机信息系统的属性之间的相关性。提出一种利用属性相关性来进行随机信息系统知识约简的方法并给出基于该方法进行知识约简的算法。

关键词: 随机信息系统, 相关性, 信息熵, 知识约简
