RAG 详解:用检索到的上下文来 grounding LLMs,以防止幻觉

检索增强生成(RAG)是一种通过在回答问题时为大型语言模型(LLMs)提供相关的、事实性的上下文来增强其能力的技术。该过程包括嵌入用户的问题,在向量数据库中搜索最相关的文档片段,然后构建一个提示词,指示 LLM 仅根据提供的上下文来回答。这种方法旨在通过将 LLM 的响应 grounding 在特定的、检索到的信息上来防止幻觉,其中 `top-k`(用于检索)和 `chunk size`(用于上下文管理)等参数是关键的调整旋钮。 AI

影响 通过将响应 grounding 在特定数据中,增强了 LLM 的准确性和可靠性,减少了用户的幻觉。

    <p>An LLM only knows what it saw in training. It doesn't know your company wiki, last week's news, or the PDF you just uploaded. Ask it anyway and it either refuses or — worse — confidently makes something up.</p> <p><strong>RAG</strong> (Retrieval-Augmented Generation) fixes tha…
