Abstract

Large margin classifiers have been shown to be very useful in many applications. The Support Vector Machine is a canonical example of large margin classifiers. Despite their flexibility and ability in handling high dimensional data, many large margin classifiers have serious drawbacks when the data are noisy, especially when there are outliers in the data. In this paper, we propose a new weighted large margin classification technique. The weights are chosen adaptively with data. The proposed classifiers are shown to be robust to outliers and thus are able to produce more accurate classification results.

摘要

大间隔分类器在许多应用中已被证明非常有用。支持向量机是大间隔分类器的一个典型例子。尽管它们在处理高维数据方面具有灵活性和能力,但当数据存在噪声时,尤其是数据中存在离群值时,许多大间隔分类器存在严重缺陷。在本文中,我们提出了一种新的加权大间隔分类技术。权重是根据数据自适应选择的。所提出的分类器被证明对离群值具有鲁棒性,因此能够产生更准确的分类结果。
