摘要:

多模态大语言模型(MLLMs)展现出卓越的图文能力,但其广泛应用面临高成本训练与适配的挑战。现有方法通常需要昂贵的语言模型重训练,且适配性有限。此外,当前对零样本性能提升的关注,无法为任务特定调优提供足够指导。我们提出CROME,一种高效的视觉-语言指令调优框架。它采用新型门控跨模态适配器,在输入冻结的大语言模型(LLM)之前有效融合视觉与文本表示。该轻量适配器仅需极少参数训练,即可实现高效跨模态理解。值得注意的是,CROME在标准视觉问答与指令遵循基准上展现出更优的零样本性能。此外,它的微调参数效率极高,可与任务特定的专用最优方法相媲美。CROME证明了大语言模型前对齐在构建可扩展、高适配性且参数高效的多模态模型方面的潜力。

英文摘要:

Multimodal Large Language Models (MLLMs) demonstrate remarkable image-language capabilities, but their widespread use faces challenges in cost-effective training and adaptation. Existing approaches often necessitate expensive language model retraining and limited adaptability. Additionally, the current focus on zero-shot performance improvements offers insufficient guidance for task-specific tuning. We propose CROME, an efficient vision-language instruction tuning framework. It features a novel gated cross-modal adapter that effectively combines visual and textual representations prior to input into a frozen LLM. This lightweight adapter, trained with minimal parameters, enables efficient cross-modal understanding. Notably, CROME demonstrates superior zero-shot performance on standard visual question answering and instruction-following benchmarks. Moreover, it yields fine-tuning with exceptional parameter efficiency, competing with task-specific specialist state-of-the-art methods. CROME demonstrates the potential of pre-LM alignment for building scalable, adaptable, and parameter-efficient multimodal models.
