摘要
基于商空间的粒度计算理论是目前三个主要的粒度计算理论之一。主要讨论商空间理论中的结构问题,并与粗糙集方法进行比较,指出结构在粒度计算理论中的重要性。讨论如何从结构着手来建立商空间模型。文中给出了从结构上取不同粒度来构造商空间的新方法,最后通过相关例子说明所提出的方法的合理性、可行性。
The theory of granule computing based on the quotient space is one of the three main granule computing theories. In this paper discuss mostly the question of the structure of the quotient space theory. Comparing with rough set theory, point out the importance of the structure in granule computing theory. Next diseuss how to build a model of the quotient space from the structure. A new method of constructing the quotient space by choosing different granules is also presented in this paper. And finally, proves the rationality and feasibility of the new method by some examples.
