ICRA 2026poster

Point cloud single object tracking is critical in autonomous driving. However, current methods heavily rely on frame-by-frame human annotations, which do not scale well with the growing amount of unlabeled LiDAR data. In this paper, we propose the first self-supervised point cloud single object trac…

Semantic Representation Attack against Aligned Large Language Models

Jiawei Lian, Jianhong Pan, Lefan Wang, Yi Wang, Shaohui Mei, Lap-Pui Chau

NeurIPS 2025poster

Large Language Models (LLMs) increasingly employ alignment techniques to prevent harmful outputs. Despite these safeguards, attackers can circumvent them by crafting prompts that induce LLMs to generate harmful content. Current methods typically target exact affirmative responses, suffering from lim…
