数据过滤算法的一种改进

The Improvement of An Approach for Data Filtering

本文深入地分析了Xuri Yin等人提出的一种数据过滤算法,指出其中欠缺之处,并对该算法作了改进和理论分析。

In this paper, an approach for data filtering based on rough set theory is deeply investigated. And we improve this approach, then an algorithm on the base of the approach is proposed in order to keep essential information and reduce granularity to a certain extent. Finally a theoretical analysis of this algorithm is made.
