知识的属性扰动与属性扰动定理

摘要

By using the dynamic characteristic of one direction S-rough sets(one direction singular rough sets)and dual of one direction S-rough sets(dual of one direction singular rough sets),the concepts of attribute disturbance of knowledge,the attribute disturbance degree of knowledge,and the disturbance coefficient of knowledge are given.By employing these concepts,the cardinal order theorem of the attribute disturbance knowledge,the unit circle theorem of the attribute disturbance knowledge,and the discernible theorem of the attribute disturbance knowledge are presented.
