ColaVLA: Leveraging Cognitive Latent Reasoning for Hierarchical Parallel Trajectory Planning in Autonomous Driving

Qihang Peng, Xuesong Chen, Chenye Yang, Shaoshuai Shi, Hongsheng Li

CVPR 2026

Autonomous driving requires generating safe and reliable trajectories from complex multimodal inputs. Traditional modular pipelines separate perception, prediction, and planning, while recent end-to-end (E2E) systems learn them jointly. Vision-language models (VLMs) further enrich this paradigm by i

Efficient Preference Poisoning Attack on Offline RLHF

Chenye Yang, Weiyu Xu, Lifeng Lai

ICML 2026poster

Offline Reinforcement Learning from Human Feedback (RLHF) pipelines such as Direct Preference Optimization (DPO) train on a pre-collected preference dataset, which makes them vulnerable to preference poisoning attack. We study label flip attacks against log-linear DPO. We first illustrate that flipp…
