多向量嵌入被证明比单向量嵌入更具表现力

一篇新发表在arXiv上的论文将多向量(MV)嵌入的概念引入为与单向量(SV)嵌入相比,神经信息检索更具表现力的范式。该研究正式证明了使用多个向量表示数据并使用Chamfer相似度的MV嵌入,相比依赖内积相似度的SV嵌入具有显著优势。研究结果确立了表示大小上的强烈分离,证实了信息检索界长期以来的观点,即MV嵌入可以捕捉SV嵌入无法近似表示的相似性。 AI

影响 这项研究为多向量嵌入在信息检索中的优越性提供了理论支持,可能影响未来的模型架构和检索系统设计。

    多向量嵌入在证明上比单向量嵌入更具表现力

    Multi-vector (MV) embeddings have become a powerful paradigm in neural information retrieval (IR), achieving high retrieval accuracy by representing data with multiple vectors and scoring them via the non-linear Chamfer similarity. Despite their widely perceived superiority over …
