摘    要:基于粗糙集的属性约简算法,先找出记录比较表中含元素1最少的行,若某行元素为1,则该元素所在列对应的属性须包含在属性约简中,否则从该若干行中找出该元素个数最多的列,再从表中删去所选列中该元素对应的行及该列,剩余部分再构成新记录比较表.重复上步骤直至比较表为空.全部依次选出的各列即构成属性约简.

关 键 词:粗糙集  属性约简  记录比较表

Abstract:The algorithm for attribute reduction is based on the record comparison table.Firstly,find out the line which includes value "1" is the least.If the value the line contains is only one,the attribute that the row corresponds is included in the attribute reduction.Otherwise,find out the row which includes value "1" is the most.Secondly delete line that the found row corresponds and the row.Finally,the remainders construct a new record comparison table.Repeat the steps,until the table is null.All the rows selected are redacted attribute.
Keywords:Rough set  Attributes reduction  Report comparison table
