| 摘 要： | 考虑到不同属性之间的重要性,利用粗糙集理论对模糊信息表或信息表中的不同属性之间(特别是定量属性与定性属性之间)进行耦合,提出一种计算不同属性间相似度的计算方法,即基于粗糙集属性重要性的模糊聚类方法,解决模糊信息表或信息表中属性值定量与定性描述并存情况下的聚类问题,并根据原类结果建立决策表.

| Abstract: | A new method was proposed for calculating the similarity of different attributes to each other,i.e.,the fuzzy clustering decision based on the significance of attributers by considering the significance of the different attributes and then coupling these attributes allocated in the fuzzy information table or information table(especially the quantitative attributes and the qualitative attributes) with rough sets theory.Thus the problem of clustering the quantitative attributes and the qualitative attributes ... |
