论文摘要
深度神经网络(DNN)在大规模注释的数据集的帮助下在许多任务上取得了巨大成功。但是,标记大规模数据可能非常昂贵且容易出错,因此很难保证注释质量(即具有嘈杂的标签)。对这些标有数据集的嘈杂培训可能会对它们的概括性能恶化。现有方法要么依赖复杂的训练阶段部门,要么带来过多的计算以改善边际性能。在本文中,我们提出了一个时间校准的正则化(TCR),其中我们利用原始标签和上一个时代中的预测一起使DNN继承了它在很少的开销中所学到的简单模式。我们对各种神经网络架构和数据集进行了广泛的实验,发现它始终增强了DNN对标记噪声的鲁棒性。
Deep neural networks (DNNs) exhibit great success on many tasks with the help of large-scale well annotated datasets. However, labeling large-scale data can be very costly and error-prone so that it is difficult to guarantee the annotation quality (i.e., having noisy labels). Training on these noisy labeled datasets may adversely deteriorate their generalization performance. Existing methods either rely on complex training stage division or bring too much computation for marginal performance improvement. In this paper, we propose a Temporal Calibrated Regularization (TCR), in which we utilize the original labels and the predictions in the previous epoch together to make DNN inherit the simple pattern it has learned with little overhead. We conduct extensive experiments on various neural network architectures and datasets, and find that it consistently enhances the robustness of DNNs to label noise.
