摘要
对粗糙集表征的属性重要度进行了深入研究,针对原有基于粗糙集理论的属性权重确立方法的不足,综合考察属性集中条件属性的整体重要度和系统中条件属性的个体重要度,提出了新的基于粗糙集理论的属性权重确定方法,提高了方法的普适性和可解释性.
This article deeply studies the attribute importance represented by rough set. Considering the drawbacks of the existing methods of attribute weight assignment based on rough set and both the overall and individual significance degree of each attribute in the conditional attributes, this article proposes a new method of attribute weight assignment based on rough set, which is assumed to be more universal interpretable.
