Summary: Large Language Models (LLMs) have significantly advanced natural language processing (NLP) with their impressive language understanding and generation capabilities. However, their performance may be suboptimal for domain-specific tasks that require specialized knowledge due to limited exposure to the related data. Additionally, the lack of transparency of most state-of-the-art (SOTA) LLMs, which can only be accessed via APIs, impedes further fine-tuning with domain custom data. Moreover, providing private data to the LLMs' owner leads to data privacy problems. To address these challenges, we propose the novel Parametric Knowledge Guiding (PKG) framework, which equips LLMs with a knowledge-guiding module to access relevant knowledge without altering the LLMs' parameters. Our PKG is based on open-source "white-box" language models, allowing offline memory of any knowledge that LLMs require. We demonstrate that our PKG framework can enhance the performance of "black-box" LLMs on a range of domain knowledge-intensive tasks that require factual (+7.9%), tabular (+11.9%), medical (+3.0%), and multimodal (+8.1%) knowledge.
A: 这篇论文提出了一个名为Parametric Knowledge Guiding (PKG)的新框架,旨在解决以下主要问题:
PKG框架通过为LLMs提供一个知识引导模块来解决这些问题,该模块可以在不改变LLMs参数的情况下访问相关知识。这个框架基于开源的“白盒”语言模型,允许离线存储LLMs所需的任何知识。论文展示了PKG框架如何增强“黑盒”LLMs在需要事实(+7.9%)、表格(+11.9%)、医学(+3.0%)和多模态(+8.1%)知识的领域知识密集型任务上的性能。
