English(EN) EigenLI: Spectral Approximations to Late Interaction

EigenLI框架为后期交互模型提供谱近似

作者 PulseAugur 编辑部 · [2 个来源] · 2026-09-07 14:41

研究人员开发了EigenLI，一个用于近似信息检索中后期交互模型的新框架。该方法利用文档标记嵌入固有的低秩结构来压缩表示，显著降低了索引成本和存储占用。EigenLI识别文档内的主要特征方向，以创建简化的交互表示，在实证测试中优于传统的聚类和池化方法。 AI

影响这项研究通过减少计算和存储开销，有望带来更高效、更具成本效益的信息检索系统。

EigenLI：晚期交互的谱近似

Late-interaction models such as ColBERT achieve strong effectiveness by representing each document with many token-level vectors, but this expressivity leads to large indexing cost, storage footprints and expensive MaxSim scoring. We show that late-interaction representations exh…
