English(EN) GRASP: Group-Adaptive Hybrid RL-SFT Post-Training for Medical VQA without Reasoning Annotations

新的GRASP方法增强了医疗VQA的视觉语言模型能力

研究人员开发了GRASP,一种新颖的后训练方法,用于将通用视觉语言模型(VLMs)适配到医疗视觉问答(VQA)任务中。该方法在每次更新中结合了监督微调(SFT)和强化学习(RL),仅使用简短答案,并根据问题难度调整两种方法之间的平衡。GRASP能够以最少的参数调整有效地训练Qwen3-VL-8B、InternVL3-8B和Gemma 3-4B等模型,在领域内和领域外的医疗VQA任务上均优于现有方法。 AI

影响 这项研究通过提高医学图像分析的准确性,有望改善人工智能在医疗保健领域的诊断能力。
