| 摘 要： | 知识约简是粗糙集理论的重要研究内容.针对不同的粗糙集模型和约简定义,给出相应的知识约简方法一直是知识约简的主要任务.以分辩函数法为代表的各种符号值信息系统知识约简方法已得到深入研究.将分辨函数引入模糊信息系统,得到相应的知识约简分辨函数法,并通过实例分析说明了该方法的具体计算步骤.这为从模糊信息系统中获取知识提供了一种有效的粗糙集方法. |
| 关 键 词： | 模糊信息系统 分辨函数 粗糙集 约简 |

| Abstract: | Knowledge reduction is one of important issues in rough set theory.Based on rough set models and knowledge reduction definitions,the corresponding reduction methods are researched in classic rough sets,in which the discernibility matrix or discernibility function plays an important role.In fuzzy information systems,some basic rough set models are presented.However,knowledge reduction methods need to be studied more.The discernibility function based reduction method is proposed.Example analysis illustrates the main steps of the presented discernibility function reduction approach.This method is efficient to knowledge acquisition from fuzzy information systems. |
| Keywords: | fuzzy information system discernibility function rough set reduction |
