理解长上下文的视觉信息仍然是视觉语言模型面临的根本性挑战,特别是在代理任务如GUI控制和网页导航中。尽管网页和GUI环境本质上是结构化的文档,但当前的VLMs通常在其训练目标中忽视了以决策为导向的文档理解。现有的方法主要扩展视觉嵌入以处理长且高分辨率的输入,但这些方法内存消耗大,不适用于本地部署的解决方案。为了解决这些问题,我们提出了SCoPE VLM,一种文档导航专家,利用新颖的滚动链机制来选择性地和递归地导航文档,仅专注于相关部分。我们引入了专门的数据生成管道来构建信息丰富的滚动链轨迹和Episodic Group Relative Policy Optimization,一种定制的强化学习方法,以弥合训练和推理之间的差距。我们的方法显著减少了内存使用,并有效建模了人类般的阅读行为。据我们所知,SCoPE VLM是第一个明确建模多页文档问答中代理阅读模式的框架,推动了多模态代理的能力。
英文摘要:
Understanding long-context visual information remains a fundamental challenge for vision-language models, particularly in agentic tasks such as GUI control and web navigation. While web pages and GUI environments are inherently structured documents, current VLMs typically neglect decision-oriented document understanding in their training objectives. Existing approaches primarily extend visual embeddings to process long, high-resolution inputs, but these methods are memory-intensive and impractical for locally deployable solutions. To address these issues, we propose SCoPE VLM, a document navigation expert that leverages a novel Chain of Scroll mechanism to selectively and recursively navigate documents, focusing exclusively on relevant segments. We introduce a dedicated data generation pipeline to construct informative Chain of Scroll trajectories and Episodic Group Relative Policy Optimization, a tailored reinforcement learning method to bridge the gap between training and inference. Our method substantially reduces memory usage and effectively models human-like reading behaviors. To the best of our knowledge, SCoPE VLM is the first framework to explicitly model agentic reading patterns in multi-page document question answering, advancing the capabilities of multimodal agents.
