Improving Adversarial Transferability via Model Alignment

no code implementations30 Nov 2023 Avery Ma, Amir-Massoud Farahmand, Yangchen Pan, Philip Torr, Jindong Gu

During the alignment process, the parameters of the source model are fine-tuned to minimize an alignment loss.

Understanding the robustness difference between stochastic gradient descent and adaptive gradient methods

1 code implementation13 Aug 2023 Avery Ma, Yangchen Pan, Amir-Massoud Farahmand

In the context of deep learning, our experiments show that SGD-trained neural networks have smaller Lipschitz constants, explaining the better robustness to input perturbations than those trained with adaptive gradient methods.

SAGE: Saliency-Guided Mixup with Optimal Rearrangements

1 code implementation31 Oct 2022 Avery Ma, Nikita Dvornik, Ran Zhang, Leila Pishdad, Konstantinos G. Derpanis, Afsaneh Fazly

For image classification, the most popular data augmentation techniques range from simple photometric and geometrical transformations, to more complex methods that use visual saliency to craft new training examples.
