摘要:

研究对训练分布和测试分布之间的变化具有鲁棒性的机器学习算法是一个活跃的研究领域。在本文中,我们探讨了一种特殊类型的数据集转移,我们称之为类依赖域转移。它的特点是:输入数据因果地依赖于标签,数据中的移位完全由一个已知的变量解释,控制移位的变量可以依赖于标签,标签分布中没有移位。我们定义了一个简单的优化问题的信息理论约束,并试图解决它与神经网络。在一个玩具数据集上的实验表明,该方法能够学习到鲁棒的分类器,这些分类器可以很好地推广到未知的领域。

英文摘要:

Investigation of machine learning algorithms robust to changes between the training and test distributions is an active area of research. In this paper we explore a special type of dataset shift which we call class-dependent domain shift. It is characterized by the following features: the input data causally depends on the label, the shift in the data is fully explained by a known variable, the variable which controls the shift can depend on the label, there is no shift in the label distribution. We define a simple optimization problem with an information theoretic constraint and attempt to solve it with neural networks. Experiments on a toy dataset demonstrate the proposed method is able to learn robust classifiers which generalize well to unseen domains.
