GDA: Generalized Diffusion for Robust Test-time Adaptation

no code implementations29 Mar 2024 Yun-Yun Tsai, Fu-Chen Chen, Albert Y. C. Chen, Junfeng Yang, Che-Chun Su, Min Sun, Cheng-Hao Kuo

For vision tasks, recent studies have shown that test-time adaptation employing diffusion models can achieve state-of-the-art accuracy improvements on OOD samples by generating new samples that align with the model's domain without the need to modify the model's weights.

Test-time Detection and Repair of Adversarial Samples via Masked Autoencoder

no code implementations22 Mar 2023 Yun-Yun Tsai, Ju-Chin Chao, Albert Wen, Zhaoyuan Yang, Chengzhi Mao, Tapan Shah, Junfeng Yang

Test-time defenses solve these issues but most existing test-time defenses require adapting the model weights, therefore they do not work on frozen models and complicate model memory management.

CARBEN: Composite Adversarial Robustness Benchmark

1 code implementation16 Jul 2022 Lei Hsiung, Yun-Yun Tsai, Pin-Yu Chen, Tsung-Yi Ho

Prior literature on adversarial attack methods has mainly focused on attacking with and defending against a single threat model, e. g., perturbations bounded in Lp ball.

Towards Compositional Adversarial Robustness: Generalizing Adversarial Training to Composite Semantic Perturbations

1 code implementation CVPR 2023 Lei Hsiung, Yun-Yun Tsai, Pin-Yu Chen, Tsung-Yi Ho

We then propose generalized adversarial training (GAT) to extend model robustness from $\ell_{p}$-ball to composite semantic perturbations, such as the combination of Hue, Saturation, Brightness, Contrast, and Rotation.

Generalizing Adversarial Training to Composite Semantic Perturbations

no code implementations ICML Workshop AML 2021 Yun-Yun Tsai, Lei Hsiung, Pin-Yu Chen, Tsung-Yi Ho

We then propose generalized adversarial training (GAT) to extend model robustness from $\ell_{p}$ norm to composite semantic perturbations, such as Hue, Saturation, Brightness, Contrast, and Rotation.
