AI总结:

本文提出多模态上下文微调范式MMICT,通过统一模块M-Hub捕获多模态特征并设计多种上下文演示,使多模态大模型能利用上下文示例进行微调,在多个下游任务上显著超越传统微调和普通ICT方法。

摘要:

尽管上下文学习(ICL)为大型语言模型(LLMs)带来了显著的性能提升,但其改进幅度仍低于在下游任务上进行微调。本文提出了多模态上下文微调(MMICT),这是一种新颖的多模态微调范式,通过充分利用多模态大型语言模型(MM-LLMs)具有前景的ICL能力来增强多模态微调。我们提出了多模态中心(M-Hub),这是一个统一的模块,可根据不同的输入和目标捕获各种多模态特征。基于M-Hub,MMICT使MM-LLMs能够从上下文视觉引导的文本特征中学习,并随后生成以文本引导的视觉特征为条件的输出。此外,利用M-Hub的灵活性,我们设计了多种上下文演示。在多种下游多模态任务上的大量实验表明,MMICT显著优于传统的微调策略以及直接将不同模态的所有信息拼接作为输入的普通ICT方法。我们的实现可在以下地址获取:https://github.com/KDEGroup/MMICT。

英文摘要:

Although In-Context Learning (ICL) brings remarkable performance gains to Large Language Models (LLMs), the improvements remain lower than fine-tuning on downstream tasks. This paper introduces Multi-Modal In-Context Tuning (MMICT), a novel multi-modal fine-tuning paradigm that boosts multi-modal fine-tuning by fully leveraging the promising ICL capability of multi-modal LLMs (MM-LLMs). We propose the Multi-Modal Hub (M-Hub), a unified module that captures various multi-modal features according to different inputs and objectives. Based on M-Hub, MMICT enables MM-LLMs to learn from in-context visual-guided textual features and subsequently generate outputs conditioned on the textual-guided visual features. Moreover, leveraging the flexibility of M-Hub, we design a variety of in-context demonstrations. Extensive experiments on a diverse range of downstream multi-modal tasks demonstrate that MMICT significantly outperforms traditional fine-tuning strategy and the vanilla ICT method that directly takes the concatenation of all information from different modalities as input. Our implementation is available at: https://github.com/KDEGroup/MMICT.
