基于逻辑判别式(LD,Logistic Discrimination),提出一种叫做LDRC(LD based Rare-class Classification)方法用于提升LD在稀有类问题中的泛化性能.为了充分考虑稀有类的特性,构建了一种新目标函数RPM(Recall and Precision based M etri...
提出了一种快速的稀有类检测算法——CATION(rare category detection algorithm based on weightedboundary degree).通过使用加权边界度(weighted boundary degree,简称WBD)这一新的稀有类检测标准,该算法可利用反向k近邻的特性来寻...
