薛贞霞 %A 张素玲 %A 刘三阳 %J 计算机科学 %D 2008 %I %X Using data sets that contain very few instances of the positive class usually produces biased classifiers and has a lower predictive accuracy over the positive class(usually the more important class)than over the negative class.Proposed a classification method for imbalance problem.This approach obtains maximum separation ratio to separate two class instances with a single sphere.Moreover,this method applies a fuzzy membership to each input point such that different input points can make different contribut... %K Imbalanced data set %K Weighted-class %K Fuzzy membership %K Classification algorithm
