摘要： 围绕不可区分关系和相对正区域两个核心概念,通过知识之间的依赖程度,提出了粗糙集数据分析的算法,通过比较属性约简的数目,选择最少属性数量的约简结果.利用MATLAB处理集合函数的优势,得到了求取相对核、上(下)近似、等价关系、相对重要度、属性相对约简、范畴相对约简、最小决策规则等的各种算法的程序实现.实现了MATLAB仿真工具箱设计.利用图形用户界面(GUI)方法,设计了良好的人-机交互系统的主界面.最后给出实际例子的程序运行结果,对推动粗糙集理论在具体实践中应用和普及,具有实际意义.

Abstract: The two kernel concepts, indiscernibility relation and relative positive region, are focused on. An algorithm is proposed to analyze the rough set data analysis system, according to the mutual dependency between different kinds of knowledge. The numbers of reduced attributes are compared to pick out a reduction result involving the minimum number of attributes. Taking the advantage of MATLAB in dealing with set functions, the program realizations of many algorithms are given to solve relative core, upper approximation, lower approximation, equivalence relation, relative significance level, relative reduction of attributes, relative reduction of domain and minimal decision rules, thus designing the MATLAB simulation tool. By way of graphical user interface (GUI), the favorable main interface of man-machine interaction system is designed. An example resulting from running is given, which shows the practical significance to the applications of rough set theory.
