论文摘要
我们介绍了一组图像转换,可以用作腐败来评估模型的鲁棒性以及用于培训神经网络的数据增强机制。所提出的转换的主要区别在于,与现有的方法(例如共同腐败)不同,场景的几何形状被纳入了转换中 - 从而导致腐败更可能发生在现实世界中。我们还引入了一组语义腐败(例如自然对象遮挡)。我们显示这些转换是“有效的”(可以在即时计算),“可扩展”(可以在大多数图像数据集上应用),揭示现有模型的漏洞,并且在用作“ 3D数据增强”机制时,可以有效地使模型更强大。对几个任务和数据集的评估表明,将3D信息纳入基准测试和培训为鲁棒性研究提供了有希望的方向。
We introduce a set of image transformations that can be used as corruptions to evaluate the robustness of models as well as data augmentation mechanisms for training neural networks. The primary distinction of the proposed transformations is that, unlike existing approaches such as Common Corruptions, the geometry of the scene is incorporated in the transformations -- thus leading to corruptions that are more likely to occur in the real world. We also introduce a set of semantic corruptions (e.g. natural object occlusions). We show these transformations are `efficient' (can be computed on-the-fly), `extendable' (can be applied on most image datasets), expose vulnerability of existing models, and can effectively make models more robust when employed as `3D data augmentation' mechanisms. The evaluations on several tasks and datasets suggest incorporating 3D information into benchmarking and training opens up a promising direction for robustness research.
