论文摘要
无监督的域适应性(UDA)需要训练过程中具有干净地面真相标签的源域样品。准确地标记大量源域样品是耗时且费力的。另一种选择是利用带有嘈杂标签的样品进行培训。但是,使用嘈杂标签的培训可以大大降低UDA的性能。在本文中,我们解决了一个问题,即学习UDA模型仅通过访问嘈杂的标签,并提出了一种名为“强大的本地保存和全球对齐网络(RLPGA)”的新方法。 RLPGA从两个方面提高了标签噪声的鲁棒性。一种是通过基于理论的损失函数来学习分类器。另一个是由拟议的本地保存模块构建两个邻接重量矩阵和两个负重量矩阵,以保留输入数据的局部拓扑结构。我们对拟议的RLPGA的鲁棒性进行了理论分析,并证明基于理论的鲁棒性损失和局部保存模块有益于降低目标域的经验风险。一系列实证研究表明了我们提出的RLPGA的有效性。
Unsupervised domain adaptation (UDA) requires source domain samples with clean ground truth labels during training. Accurately labeling a large number of source domain samples is time-consuming and laborious. An alternative is to utilize samples with noisy labels for training. However, training with noisy labels can greatly reduce the performance of UDA. In this paper, we address the problem that learning UDA models only with access to noisy labels and propose a novel method called robust local preserving and global aligning network (RLPGA). RLPGA improves the robustness of the label noise from two aspects. One is learning a classifier by a robust informative-theoretic-based loss function. The other is constructing two adjacency weight matrices and two negative weight matrices by the proposed local preserving module to preserve the local topology structures of input data. We conduct theoretical analysis on the robustness of the proposed RLPGA and prove that the robust informative-theoretic-based loss and the local preserving module are beneficial to reduce the empirical risk of the target domain. A series of empirical studies show the effectiveness of our proposed RLPGA.
