Unraveling Batch Normalization for Realistic Test-Time Adaptation

1 code implementation15 Dec 2023 Zixian Su, Jingwei Guo, Kai Yao, Xi Yang, Qiufeng Wang, Kaizhu Huang

While recent test-time adaptations exhibit efficacy by adjusting batch normalization to narrow domain disparities, their effectiveness diminishes with realistic mini-batches due to inaccurate target estimation.

Polar-Doc: One-Stage Document Dewarping with Multi-Scope Constraints under Polar Representation

no code implementations13 Dec 2023 Weiguang Zhang, Qiufeng Wang, Kaizhu Huang

While Cartesian coordinates are typically leveraged by state-of-the-art approaches to learn a group of deformation control points, such representation is not efficient for dewarping model to learn the deformation information.

Perturbation Diversity Certificates Robust Generalisation

no code implementations29 Sep 2021 Zhuang Qian, Shufei Zhang, Kaizhu Huang, Qiufeng Wang, Bin Gu, Huan Xiong, Xinping Yi

It is possibly due to the fact that the conventional adversarial training methods generate adversarial perturbations usually in a supervised way, so that the adversarial samples are highly biased towards the decision boundary, resulting in an inhomogeneous data distribution.

Improving Model Robustness with Latent Distribution Locally and Globally

1 code implementation8 Jul 2021 Zhuang Qian, Shufei Zhang, Kaizhu Huang, Qiufeng Wang, Rui Zhang, Xinping Yi

The proposed adversarial training with latent distribution (ATLD) method defends against adversarial attacks by crafting LMAEs with the latent manifold in an unsupervised manner.
