📝 摘要(中文)
多模态大语言模型(MLLMs)在处理视觉任务方面表现出色,但其黑箱推理过程仍然不透明,导致模型难以解释并出现幻觉现象。本文提出了Fact,一个新颖的范式,用于生成忠实、简洁且可转移的多模态推理,以教导MLLMs。该范式通过可验证的视觉编程生成可执行代码,确保推理的忠实性和精确性。通过修剪、合并和桥接等操作,进一步增强推理的简洁性,并过滤可从编程范式转移到端到端范式的推理,以确保可转移性。实验结果表明,该方法在不同参数规模的模型上均表现优越,显著提升了模型的组合推理和泛化能力,同时减少了幻觉现象。

📄 摘要(原文)
The remarkable performance of Multimodal Large Language Models (MLLMs) has unequivocally demonstrated their proficient understanding capabilities in handling a wide array of visual tasks. Nevertheless, the opaque nature of their black-box reasoning processes persists as an enigma, rendering them uninterpretable and struggling with hallucination. Their ability to execute intricate compositional reasoning tasks is also constrained, culminating in a stagnation of learning progression for these models. In this work, we introduce Fact, a novel paradigm designed to generate multimodal rationales that are faithful, concise, and transferable for teaching MLLMs. This paradigm utilizes verifiable visual programming to generate executable code guaranteeing faithfulness and precision. Subsequently, through a series of operations including pruning, merging, and bridging, the rationale enhances its conciseness. Furthermore, we filter rationales that can be transferred to end-to-end paradigms from programming paradigms to guarantee transferability. Empirical evidence from experiments demonstrates the superiority of our method across models of varying parameter sizes, significantly enhancing their compositional reasoning and generalization ability. Our approach also reduces hallucinations owing to its high correlation between images and text.
