On the Adversarial Risk of Test Time Adaptation: An Investigation into Realistic Test-Time Data Poisoning

no code implementations7 Oct 2024 Yongyi Su, Yushu Li, Nanqing Liu, Kui Jia, Xulei Yang, Chuan-Sheng Foo, Xun Xu

We then propose an effective and realistic attack method that better produces poisoned samples without access to benign samples, and derive an effective in-distribution attack objective.

Exploring Human-in-the-Loop Test-Time Adaptation by Synergizing Active Learning and Model Selection

no code implementations29 May 2024 Yushu Li, Yongyi Su, Xulei Yang, Kui Jia, Xun Xu

In this work, we are motivated by a pitfall of TTA, i. e. sensitivity to hyper-parameters, and propose to approach HILTTA by synergizing active learning and model selection.
