Evaluating Adversarial Robustness in the Spatial Frequency Domain

no code implementations10 May 2024 Keng-Hsin Liao, Chin-Yuan Yeh, Hsi-Wen Chen, Ming-Syan Chen

Convolutional Neural Networks (CNNs) have dominated the majority of computer vision tasks.

In Anticipation of Perfect Deepfake: Identity-anchored Artifact-agnostic Detection under Rebalanced Deepfake Detection Protocol

no code implementations1 May 2024 Wei-Han Wang, Chin-Yuan Yeh, Hsi-Wen Chen, De-Nian Yang, Ming-Syan Chen

To bridge this gap, we introduce the Rebalanced Deepfake Detection Protocol (RDDP) to stress-test detectors under balanced scenarios where genuine and forged examples bear similar artifacts.

Dual Adversarial Alignment for Realistic Support-Query Shift Few-shot Learning

no code implementations5 Sep 2023 Siyang Jiang, Rui Fang, Hsi-Wen Chen, Wei Ding, Ming-Syan Chen

The key feature of RSQS is that the individual samples in a meta-task are subjected to multiple distribution shifts in each meta-task.

PGADA: Perturbation-Guided Adversarial Alignment for Few-shot Learning Under the Support-Query Shift

1 code implementation8 May 2022 Siyang Jiang, Wei Ding, Hsi-Wen Chen, Ming-Syan Chen

Few-shot learning methods aim to embed the data to a low-dimensional embedding space and then classify the unseen query data to the seen support set.

Attack as the Best Defense: Nullifying Image-to-image Translation GANs via Limit-aware Adversarial Attack

1 code implementation ICCV 2021 Chin-Yuan Yeh, Hsi-Wen Chen, Hong-Han Shuai, De-Nian Yang, Ming-Syan Chen

To improve efficiency, we introduce the limit-aware random gradient-free estimation and the gradient sliding mechanism to estimate the gradient that adheres to the adversarial limit, i. e., the pixel value limitations of the adversarial example.
