本文质疑分类鲁棒性与解释鲁棒性强相关的传统观点,通过聚类评估解释鲁棒性,并提出调整解释损失景观的训练方法,发现两者并不强相关。

摘要:

本文深入探讨深度学习鲁棒性的关键领域,挑战了图像分类系统中分类鲁棒性和解释鲁棒性固有相关的传统观点。通过一种利用聚类高效评估解释鲁棒性的新颖评估方法,我们证明增强解释鲁棒性并不一定会使输入损失景观相对于解释损失变得平坦——这与平坦的损失景观指示更好的分类鲁棒性相反。为了深入探究这一矛盾,我们提出了一种开创性的训练方法,旨在调整相对于解释损失的损失景观。通过这种新的训练方法,我们发现尽管这种调整可以影响解释的鲁棒性,但它们对分类的鲁棒性没有影响。这些发现不仅挑战了两种鲁棒性之间强相关的主流假设,而且为理解损失景观与解释损失之间的关系开辟了新的途径。

英文摘要:

This paper delves into the critical area of deep learning robustness, challenging the conventional belief that classification robustness and explanation robustness in image classification systems are inherently correlated. Through a novel evaluation approach leveraging clustering for efficient assessment of explanation robustness, we demonstrate that enhancing explanation robustness does not necessarily flatten the input loss landscape with respect to explanation loss - contrary to flattened loss landscapes indicating better classification robustness. To deeply investigate this contradiction, a groundbreaking training method designed to adjust the loss landscape with respect to explanation loss is proposed. Through the new training method, we uncover that although such adjustments can impact the robustness of explanations, they do not have an influence on the robustness of classification. These findings not only challenge the prevailing assumption of a strong correlation between the two forms of robustness but also pave new pathways for understanding relationship between loss landscape and explanation loss.
