变精度覆盖粗糙集模型的推广

On the Generalization of Variable Precision Covering Rough Set Model

基于多数包含关系及误差参数β(0≤β<0.5),提出了基于对象邻域的变精度覆盖粗糙集模型,并讨论了由覆盖所得到的邻域及近似算子的性质.

Based on majority inclusion relation and error parameterβ（0≤β〈0.5）, the generalized variable precision rough set model was proposed with the help of neighborhood operations. The proper ties of the neighborhoods and approximation operators which satisfy some conditions are also researched.
