摘要

本文介绍了两种分类的统计离群值检测方法。在二值和多类分类问题上的实验表明，对于C4.5和1近邻分类器，局部去除异常值显著提高了一个或两个性能指标。此外，根据异常值的数量，提出了问题的分类方法。

Deleting or keeping outliers for classifier training?

This paper introduces two statistical outlier detection approaches by classes. Experiments on binary and multi-class classification problems reveal that the partial removal of outliers improves significantly one or two performance measures for C4.5 and 1-nearest neighbour classifiers. Also, a taxonomy of problems according to the amount of outliers is proposed.
