摘要
引入集对分析概念,提出了一种基于集对分析下的变精度Bayesian粗糙集模型,这就将经典粗糙集模型和变精度Bayesian粗糙集模型推广到了不完备信息系统,并且得到了该模型的上、下近似的一些性质.最后,给出了与该模型定义等价的一个定理.
In this paper, variable precision Bayesian rough set model based on set pair analysis is proposed by introducing the idea of set pair analysis, which extends the classical rough set model and variable precision Bayesian rough set model. And some properties about the upper approximation and the lower approximation of the model are discussed. Finally, a theorem equivalent to the definition of the model is given.
