在数字化时代，视觉信息在知识传递和决策支持中的重要性日益凸显。然而，传统的检索增强型生成（RAG）方法在处理视觉丰富信息时面临着诸多挑战。 一方面，传统的基于文本的方法无法处理视觉相关数据；另一方面，现有的视觉 RAG 方法受限于定义的固定流程，难以有效激活模型的推理能力。 来自阿里巴巴通义实验室的最新研究成果 ——VRAG-RL（Empower Vision-Perception-Based RAG for Visually Rich Information Understanding via Iterative Reasoning with Reinforcement Learning），将强化学习算法引入多模态智能体训练，借助迭代推理和视觉感知空间，全方位提升视觉语言 模型（VLMs）在检索、推理和理解视觉信息方面的能力，为纯视觉检索增强生成任务提供有效解决方案，代码、模型全面开源！ Paper 地址：arxiv.org/pdf/2505.22019 Github 地址：https://github.com/Alibaba-NLP/VRAG 为了解决现有 RAG 方法在处理视觉丰富文档时面临的挑战，尤其 ...

机器之心报道 编辑：张倩 「尽管经过 SFT 的模型可能看起来在进行推理，但它们的行为更接近于模式模仿 —— 一种缺乏泛化推理能力的伪推理形式。」 随着 OpenAI 的 o1/o3 和 Deepseek-R1 等具备强大推理能力的大语言模型相继问世，学界普遍采用「监督微调 + 强化学习」的两阶段训练范式：先通过推理数据进 行监督微调（SFT），再通过强化学习（RL）进一步提升性能。这种成功模式启发了研究人员将其优势从纯文本领域拓展到视觉 - 语言大模型（LVLM）领域。 但近日的一项研究成果却给出了一个惊人的发现：「SFT 可能会阻碍学习 —— 经常导致出现伪推理路径，而 RL 则是在促进真正的多模态推理！」 这个发现来自加州大学圣克鲁兹分校和德克萨斯大学达拉斯分校等机构的一个研究团队，他们深入探讨了「SFT+RL」这一经典范式在视觉语言模型开发中的适用 性，其中重点关注了两个核心问题：1）SFT 与 RL 在多模态推理中分别产生何种独特作用？2）这种两阶段训练对 LVLM 的推理能力是否确有必要？ 论文标题： SFT or RL?
