摘要
Ziarko在变精度粗糙集的基础上提出近似约简,进而形成决策规则.该文是在研究Ziarko的决策规则的基础上提出了近似决策规则,并与Ziarko形成的决策规则进行了比较.
In the research of inconsistent information system,Ziarko put forward the measure of quality of classification and introduced approximate reducts.Such decision rules would produce a big deviation on a part of objects.The idea of this paper is to produce the reducts first and form approximate decision rules then.
