| 摘 要： | 首先将粗集与模糊集合进行简单对比，并介绍利用粗集的概念考虑模糊集合的粗近似，定义粗模糊集合，利用模糊划分的相似性关系研究集合的近似问题，定义模糊粗集，并介绍粗模糊集合和模糊粗集的基本特性等，最后讨论知识近似模型的统一。

THEORETICAL ASPECTS AND APPLICATIONS ON ROUGH SETS (四) |
| |
| Abstract: | Compared rough sets with fuzzy theories, rough aproximation of fuzzy sets, rough fuzzy sets are defined based on the concepts of rough sets, and fuzzy rough sets are defined by studied aproximation of sets on similarities of fuzzy partition.Some properties of rough fuzzy sets and fuzzy rough sets are introduced in this paper.Finally the unity of models of knowledge aproximation is discussed. |
