MMOU: A Massive Multi-Task Omni Understanding and Reasoning Benchmark for Long and Complex Real-World Videos

Arushi Goel, Sreyan Ghosh, Vatsal Agarwal +16

Multimodal Large Language Models (MLLMs) have shown strong performance in visual and audio understanding when evaluated in isolation. However, their ability to jointly reason over…

VEGA: Learning Navigation VLAs from In-the-Wild Egocentric Video with Geometric Trajectory Supervision

Gershom Seneviratne, Yohan Abeysinghe, Jianyu An +3

We introduce VEGA, an approach for training navigation VisionLanguage-Action (VLA) models from unlabeled egocentric navigation videos. Internet-scale egocentric videos provide a sc…

Act on What You See: Unlocking Safe Social Navigation in Vision-Language-Action Models

Qingzi Wang, Xiyang Wu, Guangyao Shi +3

Safe social navigation requires robots to distinguish people from ordinary obstacles and to react before danger becomes imminent. We show that pretrained Vision-Language-Action (VL…

SABER: A Stealthy Agentic Black-Box Attack Framework for Vision-Language-Action Models

Xiyang Wu, Guangyao Shi, Qingzi Wang +3

Vision-language-action (VLA) models enable robots to follow natural-language instructions grounded in visual observations, but the instruction channel also introduces a critical vu…
