RAG 系统调试揭示了噪声、检索失败和模型知识泄露

一位开发者详细介绍了一个涉及检索增强生成 (RAG) 系统的复杂调试过程。起初,该系统似乎在性能上出现回归,但对请求负载进行逐字节的细致比较后发现,这种“回归”实际上是噪声。该开发者还发现,当语料库规模显著增加时,检索预算会失败,并发现一个 9B 参数模型将其预训练知识偷偷塞入其响应中,而这可以通过机械方式检测出来。 AI

影响 强调了 RAG 可靠性和模型遗忘方面的挑战,并提出了检测和缓解知识泄露的新方法。

排序理由 开发者详细介绍了 RAG 设置的技术调试和系统限制。

    我的 RAG 模型已读过书籍 - 按书籍划分的判决、虚假回归以及捕获 9B 泄露的先验知识

    <p>My evaluation told me my RAG had gotten worse. PASS dropped from 9/20 to 5/20<br /> between May and July. Same database, same prompts, same vLLM version, same<br /> model. I eventually diffed the stored request payloads byte by byte: <strong>63,430<br /> characters, identical<…
