摘要: 给出基于S-粗集的单向属性迁移集合,双向属性迁移集合以及单向信息系统和双向信息系统的模型;又给出属性迁移的若干性质。从Skowron提出的分辨矩阵的角度出发,给出了S-粗集中的分辨矩阵,并在此基础上提出了基于S-粗集理论上的属性约简算法。最后给出该算法在医学方面中的应用,证明了该算法的有效性。

关键词: S-粗集, 分辨矩阵, 属性迁移, 属性约简

Abstract: This PAPER puts forward the one-direction singular set,two-direction singular set;a model based on the S-rough sets information system is also given.And it discusses some features of the attribute transfer.From Skowron’s discernbility matrix point of view,discernable matrix of S-rough is proposed.Then,an attributes reduction algorithm based on the S-rough set theory for information system is rendered.Finally,the algorithm in the application of medicine is given.It has proven this algorithm validity.

Key words: singular rough set, discernbility matrix, attribute transfer, attribute reduction
