序信息系统中变精度粗糙集属性约简的Matlab实现

Experimental Computing on Attribute Reduction by Matlab in Dominance-Based Variable Precision Rough Set

根据序信息系统中变精度粗糙集的理论知识,应用Matlab程序实现序信息系统中变精度粗糙集属性约简的计算。当序信息系统变精度粗糙集考虑单个优势决策时,约简类型不受系统协调性的影响,因此进行了考虑单个优势决策的约简计算研究,并通过算例验证了程序的正确性和可行性。

According to the theory on Dominance-based variable precision rough set, we study and program Matlab codes to compute the attribute reductions and realize the variable precision rough set in ordered information systems. While a single dominance decision is considered in an ordered information system, the forms of reductions are not affected by the consistence of the system. And the attribute reductions with respect to a single decision are considered in this paper. Furthermore, cases are employed to illustrate the corrective of the program.
