AI总结:

针对多模态领域指令微调研究不足的问题,提出用仅语言GPT-4生成多模态指令数据,训练端到端多模态模型LLaVA,取得了接近GPT-4的效果并刷新Science QA基准,且公开相关资源。

摘要:

使用机器生成的指令遵循数据对大语言模型(LLM)进行指令微调,已经提升了其在新任务上的零样本能力,但这一思路在多模态领域的探索仍较少。本文首次尝试使用仅语言的GPT-4生成多模态语言-图像指令遵循数据。通过在这类生成数据上进行指令微调,我们提出了LLaVA:大语言与视觉助手,这是一个端到端训练的大多模态模型,连接视觉编码器与LLM,用于通用视觉与语言理解。我们的早期实验表明,LLaVA展现出出色的多模态对话能力,在未见过的图像/指令上有时会呈现出多模态GPT-4的行为,在合成多模态指令遵循数据集上,其相对得分达到GPT-4的85.1%。在Science QA上进行微调时,LLaVA与GPT-4的协同作用实现了92.53%的全新最优准确率。我们公开了GPT-4生成的视觉指令微调数据、我们的模型以及代码库。

英文摘要:

Instruction tuning large language models (LLMs) using machine-generated instruction-following data has improved zero-shot capabilities on new tasks, but the idea is less explored in the multimodal field. In this paper, we present the first attempt to use language-only GPT-4 to generate multimodal language-image instruction-following data. By instruction tuning on such generated data, we introduce LLaVA: Large Language and Vision Assistant, an end-to-end trained large multimodal model that connects a vision encoder and LLM for general-purpose visual and language understanding.Our early experiments show that LLaVA demonstrates impressive multimodel chat abilities, sometimes exhibiting the behaviors of multimodal GPT-4 on unseen images/instructions, and yields a 85.1% relative score compared with GPT-4 on a synthetic multimodal instruction-following dataset. When fine-tuned on Science QA, the synergy of LLaVA and GPT-4 achieves a new state-of-the-art accuracy of 92.53%. We make GPT-4 generated visual instruction tuning data, our model and code base publicly available.
