研究人员开发了DINOSAUR，一个用于近似最近邻搜索的新框架，该框架考虑了项目嵌入中的不确定性。这种方法旨在通过为每个项目和用户采样多个嵌入来改进检索系统，从而解决对热门项目的偏见并增强长尾内容的发现。该框架设计为与现有基础设施兼容，并有望在对离线召回影响最小的情况下扩展检索覆盖范围。 AI
影响 通过改进长尾内容发现和减少对热门项目的偏见来增强推荐系统。

Approximate Nearest Neighbour search indices form the backbone of real-world recommender systems, enabling real-time candidate retrieval over million-item catalogues. Typically, a single point estimate embedding is learnt for every user and every item. At serving time, the user e…
