Model Inversion Attack via Dynamic Memory Learning

no code implementations24 Aug 2023 Gege Qi, Yuefeng Chen, Xiaofeng Mao, Binyuan Hui, Xiaodan Li, Rong Zhang, Hui Xue

Model Inversion (MI) attacks aim to recover the private training data from the target model, which has raised security concerns about the deployment of DNNs in practice.

Robust Automatic Speech Recognition via WavAugment Guided Phoneme Adversarial Training

no code implementations24 Jul 2023 Gege Qi, Yuefeng Chen, Xiaofeng Mao, Xiaojun Jia, Ranjie Duan, Rong Zhang, Hui Xue

Developing a practically-robust automatic speech recognition (ASR) is challenging since the model should not only maintain the original performance on clean samples, but also achieve consistent efficacy under small volume perturbations and large domain shifts.

Towards Robust Vision Transformer

2 code implementations CVPR 2022 Xiaofeng Mao, Gege Qi, Yuefeng Chen, Xiaodan Li, Ranjie Duan, Shaokai Ye, Yuan He, Hui Xue

By using and combining robust components as building blocks of ViTs, we propose Robust Vision Transformer (RVT), which is a new vision transformer and has superior performance with strong robustness.

Stabilized Medical Image Attacks

1 code implementation9 Mar 2021 Gege Qi, Lijun Gong, Yibing Song, Kai Ma, Yefeng Zheng

However, a threat to these systems arises that adversarial attacks make CNNs vulnerable.

Stabilized Medical Attacks

no code implementations ICLR 2021 Gege Qi, Lijun Gong, Yibing Song, Kai Ma, Yefeng Zheng

We further analyze the KL-divergence of the proposed loss function and find that the loss stabilization term makes the perturbations updated towards a fixed objective spot while deviating from the ground truth.
