论文摘要
深度学习(DL)模型在许多领域取得了巨大的成功。但是,DL模型越来越面临安全性和鲁棒性问题,包括在训练阶段进行嘈杂的标签以及在测试阶段的特征分布变化。以前的工作在解决这些问题方面取得了重大进展,但重点主要是一次仅针对一个问题开发解决方案。例如,最近的工作主张使用可调稳健的损失函数来减轻标签噪声,以及数据增强(例如Augmix)来对抗分布变化。作为同时解决这两个问题的一步,我们介绍了Augloss,这是一种简单但有效的方法,可以通过统一数据增强和稳健的损失功能来对火车时间噪声标签和测试时间特征分布的变化实现稳健性。我们在现实世界数据集损坏的各种设置中进行了全面的实验,以展示与以前的最新方法相比,Augloss所取得的收益。最后,我们希望这项工作将开辟新的方向,以设计在现实世界腐败下更健壮和可靠的DL模型。
Deep Learning (DL) models achieve great successes in many domains. However, DL models increasingly face safety and robustness concerns, including noisy labeling in the training stage and feature distribution shifts in the testing stage. Previous works made significant progress in addressing these problems, but the focus has largely been on developing solutions for only one problem at a time. For example, recent work has argued for the use of tunable robust loss functions to mitigate label noise, and data augmentation (e.g., AugMix) to combat distribution shifts. As a step towards addressing both problems simultaneously, we introduce AugLoss, a simple but effective methodology that achieves robustness against both train-time noisy labeling and test-time feature distribution shifts by unifying data augmentation and robust loss functions. We conduct comprehensive experiments in varied settings of real-world dataset corruption to showcase the gains achieved by AugLoss compared to previous state-of-the-art methods. Lastly, we hope this work will open new directions for designing more robust and reliable DL models under real-world corruptions.
