本文提出SVIT,通过构建420万条高质量、多样化的视觉指令数据并设计数据选择配方,训练出SVIT-v1.5模型,在多个基准上超越现有最先进多模态大模型。

摘要:

得益于基础模型的出现,大型语言模型和视觉模型被整合起来,以获得视觉描述、问答等多模态能力。尽管现有的多模态模型在视觉理解和推理方面表现出令人印象深刻的能力,但由于高质量指令微调数据的稀缺,其局限性在很大程度上仍未得到充分探索。为了突破多模态能力的极限,我们通过构建一个包含420万条视觉指令微调数据的数据集来扩展视觉指令微调(SVIT),其中包括160万对对话问答(QA)、160万对复杂推理QA、100万对指代QA和10.6万条详细图像描述。除了数据量,所提出的数据集还具有高质量和丰富多样性的特点,这些数据是通过利用丰富的图像人工标注来提示GPT-4生成的。我们还提出了一种新的数据配方,以选择具有更好多样性和平衡性的子集,从而激发模型卓越的能力。大量实验证明,在所提出的数据集上训练的SVIT-v1.5在流行的基准测试上优于最先进的多模态大型语言模型。数据和代码可在https://github.com/BAAI-DCAI/Visual-Instruction-Tuning公开获取。

英文摘要:

Thanks to the emerging of foundation models, the large language and vision models are integrated to acquire the multimodal ability of visual captioning, question answering, etc. Although existing multimodal models present impressive performance of visual understanding and reasoning, their limits are still largely under-explored due to the scarcity of high-quality instruction tuning data. To push the limits of multimodal capability, we Scale up Visual Instruction Tuning (SVIT) by constructing a dataset of 4.2 million visual instruction tuning data including 1.6M conversation question-answer (QA) pairs, 1.6M complex reasoning QA pairs, 1.0M referring QA pairs and 106K detailed image descriptions. Besides the volume, the proposed dataset is also featured by the high quality and rich diversity, which is generated by prompting GPT-4 with the abundant manual annotations of images. We also propose a new data recipe to select subset with better diversity and balance, which evokes model's superior capabilities. Extensive experiments verify that SVIT-v1.5, trained on the proposed dataset, outperforms state-of-the-art Multimodal Large Language Models on popular benchmarks. The data and code are publicly available at https://github.com/BAAI-DCAI/Visual-Instruction-Tuning.
