This paper introduces DOBIN, a new approach to select a set of basis vectors tailored for outlier detection. DOBIN has a simple mathematical foundation and can be used as a dimension reduction tool for outlier detection tasks. We demonstrate the effectiveness of DOBIN on an extensive data repository, by comparing the performance of outlier detection methods using DOBIN and other bases. We further illustrate the utility of DOBIN as an outlier visualization tool. The R package dobin implements this basis construction.

使用DOBIN进行尺寸缩减以进行离群值检测

本文介绍了DOBIN,DOBIN是一种选择用于离群检测的基础向量的新方法。DOBIN具有简单的数学基础,可用作异常值检测任务的降维工具。通过比较使用DOBIN和其他基础的异常值检测方法的性能,我们证明了DOBIN在广泛的数据存储库中的有效性。我们进一步说明了DOBIN作为离群值可视化工具的实用性。R包dobin实现了此基础构造。
