Can Simple Averaging Defeat Modern Watermarks? Pei Y ang

Neural Information Processing Systems

For some algorithms like Tree-Ring watermarks, the extracted pattern can also forge convincing watermarks on clean images. Our quantitative and qualitative evaluations across twelve watermarking methods highlight the threat posed by steganalysis to content-agnostic watermarks and the importance of designing watermarking techniques resilient to such analytical attacks.



Reining Generalization in Offline Reinforcement Learning via Representation Distinction

Neural Information Processing Systems

Offline Reinforcement Learning (RL) aims to address the challenge of distribution shift between the dataset and the learned policy, where the value of out-of-distribution (OOD) data may be erroneously estimated due to overgeneralization.
