📝 摘要(中文)
随着大型语言模型(LLMs)和指令调优的兴起,指令调优的大型语言和视觉模型(LLVMs)逐渐成为趋势。然而,现有的LLVMs在视觉感知任务中忽视了来自专门计算机视觉(CV)模型的详细和全面的真实场景理解。为此,本文提出了一种新的LLVM,称为Mixture of All Intelligence(MoAI),它利用外部分割、检测、场景图生成(SGG)和光学字符识别(OCR)模型的辅助视觉信息。MoAI通过两个新模块:MoAI-Compressor和MoAI-Mixer进行操作,显著提升了在多个零-shot视觉语言任务中的表现,尤其是在与真实场景理解相关的任务上,而无需扩大模型规模或额外策划视觉指令调优数据集。

📄 摘要(原文)
The rise of large language models (LLMs) and instruction tuning has led to the current trend of instruction-tuned large language and vision models (LLVMs). This trend involves either meticulously curating numerous instruction tuning datasets tailored to specific objectives or enlarging LLVMs to manage vast amounts of vision language (VL) data. However, current LLVMs have disregarded the detailed and comprehensive real-world scene understanding available from specialized computer vision (CV) models in visual perception tasks such as segmentation, detection, scene graph generation (SGG), and optical character recognition (OCR). Instead, the existing LLVMs rely mainly on the large capacity and emergent capabilities of their LLM backbones. Therefore, we present a new LLVM, Mixture of All Intelligence (MoAI), which leverages auxiliary visual information obtained from the outputs of external segmentation, detection, SGG, and OCR models. MoAI operates through two newly introduced modules: MoAI-Compressor and MoAI-Mixer. After verbalizing the outputs of the external CV models, the MoAI-Compressor aligns and condenses them to efficiently use relevant auxiliary visual information for VL tasks. MoAI-Mixer then blends three types of intelligence (1) visual features, (2) auxiliary features from the external CV models, and (3) language features by utilizing the concept of Mixture of Experts. Through this integration, MoAI significantly outperforms both open-source and closed-source LLVMs in numerous zero-shot VL tasks, particularly those related to real-world scene understanding such as object existence, positions, relations, and OCR without enlarging the model size or curating extra visual instruction tuning datasets.
