2.
The irrationality of the relative reduction algorithm of rough set model based on fuzzy equation relation was pointed out and the notion of relative reduction was redefined and an improved binary version of particle swarm optimization (PSO) algorithm was used to compute the relative reduction of the hybrid decision systems.
针对基于模糊等价关系建立的粗糙集模型,指出了现有相对约简算法的不合理,重新定义了相对约简,并提出利用改进的二进制粒子群优化(PSO)算法来求混合决策系统的相对约简。
补充资料:动态模糊聚类法
分子式:
CAS号:

性质:又称动态模糊聚类法。选定一批聚类中心,其指标能反映该类的特征,将样本向最近的聚类中心聚类。再根据分类结果确定新的聚类中心,其各项指标为该类中所有样本的相应指标的平均值。然后计算前后两聚类中心的差异,如差异大于某一阈值,说明分类不合理,需修改分类,即以新的聚类中心代替旧的聚类中心,直到前后两聚类中心的差异小于某一阈值,认为分类合理,从而终止分类过程。
