摘要
粗糙集理论一直致力于研究不确定或不精确信息的数据分析问题。基于粗糙集的相关概念,对标准粗糙集模型与可变精度粗糙集模型进行了比较研究,着重描述了可变精度粗糙集模型的特点。
Rough set theory has been aiming at data analysis problems involving uncertain or imprecise information. Based on the relative concepts of rough set,the paper makes a eornparitive research between classical rough set model and variable precision rough set model, and describes especially the properties of variable precision rough set model.
