摘要:

尽管多模态大语言模型(MLLMs)在多样理解任务上取得了进展,但它们在需要多步推理的问题上表现不佳,主要原因是长上下文生成过程中视觉信息的逐渐稀释,阻碍了其在测试时扩展能力。为此,我们引入了视觉对齐潜在推理(VaLR),一种简单但有效的推理框架,通过在每个思维链推理步骤前动态生成视觉对齐的潜在标记,引导模型基于潜在空间中的感知线索进行推理。具体而言,VaLR通过对齐MLLM的中间嵌入与视觉编码器的嵌入来保留视觉知识。实验结果表明,VaLR在需要长上下文理解和精确视觉感知的广泛基准上均优于现有方法,同时表现出未在先前MLLM中观察到的测试时扩展行为。特别是,VaLR在VSI-Bench上将性能显著提升从33.0%到52.9%,比Qwen2.5-VL高出19.9个百分点。

英文摘要:

Despite recent advancements in Multi-modal Large Language Models (MLLMs) on diverse understanding tasks, these models struggle to solve problems which require extensive multi-step reasoning. This is primarily due to the progressive dilution of visual information during long-context generation, which hinders their ability to fully exploit test-time scaling. To address this issue, we introduce Vision-aligned Latent Reasoning (VaLR), a simple, yet effective reasoning framework that dynamically generates vision-aligned latent tokens before each Chain of Thought reasoning step, guiding the model to reason based on perceptual cues in the latent space. Specifically, VaLR is trained to preserve visual knowledge during reasoning by aligning intermediate embeddings of MLLM with those from vision encoders. Empirical results demonstrate that VaLR consistently outperforms existing approaches across a wide range of benchmarks requiring long-context understanding or precise visual perception, while exhibiting test-time scaling behavior not observed in prior MLLMs. In particular, VaLR improves the performance significantly from 33.0% to 52.9% on VSI-Bench, achieving a 19.9%p gain over Qwen2.5-VL.
