ARDuP: Active Region Video Diffusion for Universal Policies

Shuaiyi Huang, Mara Levy, Zhenyu Jiang +5

Sequential decision-making can be formulated as a text-conditioned video generation problem, where a video planner, guided by a text-defined goal, generates future frames visualizi…

AutoHallusion: Automatic Generation of Hallucination Benchmarks for Vision-Language Models

Xiyang Wu, Tianrui Guan, Dianqi Li +9

Large vision-language models (LVLMs) are prone to hallucinations, where certain contextual cues in an image can trigger the language module to produce overconfident and incorrect r…
