| 摘 要： | 在前面已讨论过的静态粗信息矩阵数量特征(粒度、精度)基础上,利用动态粗糙集理论,进一步给出动态粗信息粒度矩阵的三种形式,系统地讨论了静态、动态系统的粗信息粒度矩阵的特征及其关系定理,这一研究不仅完善了粗信息矩阵这一新的研究方向内容,而且为动态系统的知识挖掘提供了一个可靠的依据。

| Abstract: | This paper further gives three forms on dynamic rough information granularity matrix and discusses systematically their quantity characteristic as well as relations by combining with dynamic rough theory,based on discussed quantity characteristics(granularity,precision) with static rough information matrix.This will not only profit the research direction content of rough information matrix but also provide a reliable evidence for dynamic system knowledge mining. |
