Deep neural networks are the default choice of learning models for computer vision tasks. Extensive work has been carried out in recent years on explaining deep models for vision tasks such as classification. However, recent work has shown that it is possible for these models to produce substantially different attribution maps even when two very similar images are given to the network, raising serious questions about trustworthiness. To address this issue, we propose a robust attribution training strategy to improve attributional robustness of deep neural networks. Our method carefully analyzes the requirements for attributional robustness and introduces two new regularizers that preserve a model's attribution map during attacks. Our method surpasses state-of-the-art attributional robustness methods by a margin of approximately 3% to 9% in terms of attribution robustness measures on several datasets including MNIST, FMNIST, Flower and GTSRB.

该研究论文旨在提出一种强健的归因训练策略来提高深度神经网络的归因鲁棒性，针对近年来的研究表明，尽管这些模型被给予两张非常相似的图像，但其产生的归因图可能会有很大的不同，从而引发了对其可信度的质疑。这个方法通过引入保护模型归因图免受攻击的两个新的正则器来提高归因鲁棒性，并在多个数据集上超越了最先进的归因鲁棒性方法。
