摘要
Abstract
In view of the traditional HSSVM(hyper sphere support vector machine) in processing of imbalanced data set the minority class the problem of low recall ratio,and by introducing the maximum margin and the parameter nu,this paper proposed the NU-MMHSSVM(nu-maximum margin hyper sphere support vector machine).The algorithm takes the maximum margin as the optimization target to build a classification model,greatly improving the minority class recall.Through UCI data set classification experiments,the algorithm with the traditional HSSVM(hyper sphere support vector machine) classification accuracy is compared.The results show that the algorithm can effectively improve the imbalanced distribution of data classification accuracy.关键词
