摘要:

本文将Universum学习[1,2]的思想推广到单类学习问题。我们提出了单类Universum-SVM设置,将先验知识(以额外的数据样本的形式)到单类估计问题。这些额外的数据样本或Universum与来自单个类别(感兴趣)的(正)数据样本属于相同的应用领域,但它们遵循不同的分布。提出的单类U-SVM方法是基于二元分类和单类学习公式之间的已知联系[3]。几个实证比较来说明所提出的方法的实用性。

英文摘要:

This paper extends the idea of Universum learning [1, 2] to single-class learning problems. We propose Single Class Universum-SVM setting that incorporates a priori knowledge (in the form of additional data samples) into the single class estimation problem. These additional data samples or Universum belong to the same application domain as (positive) data samples from a single class (of interest), but they follow a different distribution. Proposed methodology for single class U-SVM is based on the known connection between binary classification and single class learning formulations [3]. Several empirical comparisons are presented to illustrate the utility of the proposed approach.
