新研究提出拓扑保持用于动态电商搜索检索

一篇新研究论文探讨了在不断添加新商品的动态电商搜索环境中维持检索质量的挑战。研究发现,更新语义标识符(SIDs)与商品之间的映射会显著降低检索性能,而这种性能下降可以通过较大的束搜索宽度来掩盖。该研究提出了一种拓扑保持原则,该原则涉及固定旧商品SIDs并插入新商品,同时进行模型热启动,从而在检索指标上取得显著改进,并在在线A/B测试中实现可衡量的提升。 AI

影响 提出了一种在动态电商环境中提高检索准确性的方法,可能对在线零售平台产生影响。

    不要重写SID图:动态电商搜索中生成式检索的拓扑保持

    Generative retrieval assigns each item a discrete semantic identifier (SID) and retrieves items by autoregressively generating SID sequences. In dynamic environments such as e-commerce, new items arrive continuously, requiring periodic updates to the SID-to-Item mapping and model…
