摘要
在给定属性序下,提出了一种基于容差关系的属性约简算法,该算法可以计算给定属性序下不完备信息系统的唯一约简。文中给出了严格的证明,并给出了实例说明。
In this paper, an attribute order was given, and an algorithm for attribute reduction based on tolerance relation was developed. With the proposed algorithm the unique attribute reduction of the incomplete information systems can be obtained. The strict proof was presented and a case study was also provided to illustrate the proposed algorithm in detail.
