| 摘 要： | 在信息系统中，我们可以用值约简算法过滤和删除冗余的条件属性值来简化信息系统决策规则的获取过程．本文介绍了值约简的基本算法，并对该算法功能进行了适当的补充．实验证明，针对那些当删除记录的一些属性后不会出现重复记录并且不会发生决策不一致的情况，这种改进后的算法十分有效，是对基本值约简算法的重要补充．

| Abstract: | In information system,we can reduce the process of obtaining decision rules with value reduction algorithm,which can filter and delete redundant conditional attribute value.In this paper,the basic value reduction algorithm is introduced,and some supplemented functions are added.Examples illustrate that the improved algorithm is very effective aiming at the circumstance of there is no repeated record and no conflict after deleting some attributes of a record.It is an important supplement for basic value reduction algorithm. |
