📝 摘要(中文)

大型多模态模型(LMMs)在视觉理解方面表现出色,但在复杂的组合推理任务中仍显不足。为此,本文提出了一种统一的视觉推理机制,使LMMs能够通过其内在能力(如定位和视觉理解)解决复杂的组合问题。与以往的快捷学习机制不同,该方法引入了类人理解-思考-回答的过程,允许模型在单次前向传播中完成所有步骤,无需多次推理或外部工具。这一设计弥合了基础视觉能力与一般问答之间的差距,鼓励LMMs为复杂视觉推理生成可信且可追溯的响应。我们还整理了334K个视觉指令样本,涵盖一般场景和文本丰富场景,并涉及多种基础视觉能力。经过训练的模型Griffon-R具备端到端的自动理解、自我思考和推理能力。

🔬 方法详解

问题定义:本文旨在解决大型多模态模型在复杂组合推理任务中的不足,现有方法通常依赖于多次推理或外部工具,导致效率低下和准确性不足。

核心思路:提出一种类人理解-思考-回答的过程,使模型能够在单次前向传播中完成所有推理步骤,从而提高推理效率和准确性。

技术框架:整体架构包括三个主要模块:理解模块负责视觉信息的解析,思考模块进行逻辑推理,回答模块生成最终的响应。这一流程确保了信息的有效流动和处理。

关键创新:最重要的创新在于引入了类人思维过程,模型不再依赖于传统的快捷学习机制,而是通过内在能力完成复杂推理,提升了模型的通用性和适应性。

关键设计:在模型设计中,采用了特定的损失函数以优化推理过程,并通过精心设计的网络结构来增强模型的理解和推理能力,确保其在复杂场景中的表现。

📄 摘要(原文)

Large Multimodal Models (LMMs) have recently demonstrated remarkable visual understanding performance on both vision-language and vision-centric tasks. However, they often fall short in integrating advanced, task-specific capabilities for compositional reasoning, which hinders their progress toward truly competent general vision models. To address this, we present a unified visual reasoning mechanism that enables LMMs to solve complicated compositional problems by leveraging their intrinsic capabilities (e.g. grounding and visual understanding capabilities). Different from the previous shortcut learning mechanism, our approach introduces a human-like understanding-thinking-answering process, allowing the model to complete all steps in a single pass forwarding without the need for multiple inferences or external tools. This design bridges the gap between foundational visual capabilities and general question answering, encouraging LMMs to generate faithful and traceable responses for complex visual reasoning. Meanwhile, we curate 334K visual instruction samples covering both general scenes and text-rich scenes and involving multiple foundational visual capabilities. Our trained model, Griffon-R, has the ability of end-to-end automatic understanding, self-thinking, and reasoning answers. Comprehensive experiments show that Griffon-R not only achieves advancing performance on complex visual reasoning benchmarks including VSR and CLEVR, but also enhances multimodal capabilities across various benchmarks like MMBench and ScienceQA.
