2nd Workshop on Multimodal Reasoning and Slow Thinking in the Large Model Era: Towards System 2 and Beyond
Sep 08 2026Official workshop site Site reachable
The MARS2 Workshop at ECCV 2026 brings together researchers from computer vision, large language models, and multimodal learning to explore multimodal reasoning and slow thinking in the era of large reasoning models (LRMs). It aims to advance open-world understanding, grounding, and robust evaluation beyond traditional closed-set paradigms, fostering collaboration on complex, real-world AI tasks.
