arXiv:2606.31599v1 Announce Type: cross Abstract: Vision-language models (VLMs) combining reinforcement learning (RL) ignite remarkable progress in multimodal reasoning, yet still struggle with medical images, which typically exhibit extremely sparse visual evidence to inform clinical decision-making. We recognize that pruning visual tokens outside the grounding region greatly enhances medical reasoning. However, a united RL framework for active visual token pruning (VTP) and medical multimodal reasoning remains unestablished. Here, we propose a dual-stream RL framework, ViToS, to fulfill toke
The continuous evolution of vision-language models and the increasing need for precise AI in critical fields like medicine drive the development of more efficient and accurate reasoning frameworks.
This work represents a concrete methodological advancement in applying reinforcement learning to multimodal medical reasoning, addressing a key limitation of existing VLMs in handling sparse visual evidence common in medical imagery.
By proposing a dual-stream reinforcement learning framework for token-sparse processing, the efficiency and accuracy of medical AI diagnostics and decision support systems could significantly improve.
