摘要:

多模态大语言模型(MLLMs)推动了视觉与语言模态的融合,已成为视觉-语言任务的主导范式。当前诸如思维链(CoT)推理等方法增强了大语言模型(LLMs)的认知能力,但将其适配到多模态大语言模型时,受到跨模态理解中幻觉风险加剧的阻碍。本文发现,当前多模态思维链方法中“边观察边思考”的范式——即推理链与视觉输入同时生成——无法缓解由误导性图像引起的幻觉。为解决这些局限,我们提出了视觉推理链(Visual Inference Chain,VIC)框架,这是一种在引入视觉输入之前仅利用文本上下文构建推理链的新方法,有效减少了跨模态偏差并增强了多模态推理准确性。综合评估表明,VIC显著提升了各类视觉相关任务上的零样本性能,在缓解幻觉的同时完善了多模态大语言模型的推理能力。我们的代码仓库可在 https://github.com/Terry-Xu-666/visual_inference_chain 获取。

英文摘要:

Multimodal large language models (MLLMs) have advanced the integration of visual and linguistic modalities, establishing themselves as the dominant paradigm for visual-language tasks. Current approaches like chain of thought (CoT) reasoning have augmented the cognitive capabilities of large language models (LLMs), yet their adaptation to MLLMs is hindered by heightened risks of hallucination in cross-modality comprehension. In this paper, we find that the thinking while looking paradigm in current multimodal CoT approaches--where reasoning chains are generated alongside visual input--fails to mitigate hallucinations caused by misleading images. To address these limitations, we propose the Visual Inference Chain (VIC) framework, a novel approach that constructs reasoning chains using textual context alone before introducing visual input, effectively reducing cross-modal biases and enhancing multimodal reasoning accuracy. Comprehensive evaluations demonstrate that VIC significantly improves zero-shot performance across various vision-related tasks, mitigating hallucinations while refining the reasoning capabilities of MLLMs. Our code repository can be found at https://github.com/Terry-Xu-666/visual_inference_chain.
