一种基于决策的数据补全方法

A Method of Recruiting Default in Data Based on the Decision

一般来说 ,在从数据库中获得有用的知识之前 ,通过采样、收集而取得的原始数据不一定适合于直接运用于知识获取 ,通常要对原始数据进行加工处理 ,对有遗漏的信息资料就要补全。文章在对粗糙集理论研究的基础上 ,运用容差关系对含有决策的数据表进行了遗漏补缺 。

Generally speaking, before acquiring useful information from database, the original data which are got by sampling and collecting may not be applied to acquiring knowledge directly. Usually, original data need to be processed and default filled. Based on the profound research of rough set theory, the decision table is default filled by using tolerance relation, which proves efficient.
