QUBO 优化解决了 RAG 问答中的证据选择问题

作者 PulseAugur 编辑部 · [2 个来源] ·

研究人员开发了一种新颖的证据选择方法，用于检索增强问答 (RAG)，将其表述为二次无约束二元优化 (QUBO) 问题。该方法旨在通过平衡相关性、需求覆盖率和其他因素，来改进互补证据段的选择，这对于复杂的多跳问题至关重要。QUBO 选择器提供了一种经济高效且可扩展的替代 LLM 选择器的方法，在 HotpotQA 基准测试上取得了有竞争力的性能，并指明了 RAG 管道的未来方向，即保留 LLM 用于语义处理，同时使用专用求解器进行上下文选择。 AI

影响 这项研究可能通过将组合证据选择与基于 LLM 的语义处理分开，从而实现更高效、可扩展的 RAG 系统。

    QUBO-Optimized Evidence Selection for Retrieval-Augmented Question Answering with Unconventional Solvers

    Retrieval-augmented question answering depends on selecting evidence passages that jointly support answer generation. However, many RAG pipelines rely on top-\(k\) ranking, where passages are selected mainly by individual relevance scores, even though multi-hop questions often re…
