| 摘 要： | 在基于联系度的粗糙集模型中引入条件属性存在重要性差异的因素,定义了不完备决策表中对象间的重要性联系度,提出了基于重要性联系度的粗糙集扩展模型.在此模型中给出了对不完备决策表进行属性约简和规则提取的算法,并以Visual C++6.0为开发工具编写了程序,进一步验证了算法的正确性和模型的可靠性.

| Abstract: | Important difference factors which conditional attributes have were introduced into the rough set model based on the connection degree.Important connection degree was defined which exist between objects among incomplete decision tables and the extended rough set model was proposed based on the important connection degree.Algorithms of reducing attributes and ruled extracting in incomplete decision tables in this model were introduced.Visual C++6.0 was used to compile a program,with which further validated t... |
