摘要
提出一种基于秩统计量的粗糙集精度的度量方法,该方法既考虑了知识颗粒块数据值的大小的信息,又考虑了论域大小,并给出这一度量的若干性质,实例表明所给出的精度度量是合理的、有效的.
An accuracy measure for rough sets based on rank statistics has been proposed ,which not Only take into consideration the information of the size of the knowledge data value of particles but also the size of the universe. Meanwhile some properties are given. It is more reasonable and effective to measure, which are illustrated by exampies.
