不平衡数据集分类方法研究

摘要

本文主要介绍了不平衡数据分类的方法，包括数据层面的方法和算法改进方面的方法；传统的分类方法的评价指标，对于不平衡数据集是不适用的，故本文最后又对不平衡数据集分类的评价指标作了简要的探讨。%This paper mainly introduces the classification method of imbalanced data sets, including the method based on data and the improvement method based on algorithm; About evaluation index of traditional classification method, the imbalanced data sets is not applicable, therefore this paper briefly discusses on the evaluation index of imbalanced data sets classification at end.
