摘要
针对基本RS模型的不足,介绍了变精度粗糙集模型,并讨论了它与基本RS模型的关系.最后,定义了变精度粗糙集模型上的属性近似依赖、近似约简.
To make up the deficiency of basic RS model,the variable precision rough set model is proposed. The relations between the variable precision model and the basic RS model are discussed and the notions of attribute dependence and reduction of attribute based on this model are also defined.
