不完备信息系统下限制容差关系模型的改进
An improved mode of limited tolerance relation under in complete information systems
【摘要】 分析了不完备信息系统下的3种粗糙集扩展关系的缺陷,提出一种可变精度的限制容差关系,并通过理论分析和实例计算验证其有效性.
【Abstract】 This paper first analyzes the limitations of three extensions of rough set under incomplete information systems and then presents an improved limited tolerance relation based on variable precision. Both theoretical analysis and experimental results are made to validate the proposed extension model.
