UniRec模型融合级联推荐阶段以提高用户参与度 · arXiv

研究人员开发了UniRec,这是一种新颖的模型,旨在通过融合推荐过程中不同阶段的信息来改进级联推荐系统。与之前专注于单阶段融合或简单跨阶段协调的方法不同,UniRec采用了统一的计算图,具有共享嵌入和双轴偏好对齐目标。这种方法确保了上游和下游阶段之间的一致性,并将成对目标重组为双向偏好证据。该模型还纳入了属性组相对正则化,以防止过度集中于高回报区域。UniRec已部署在快手平台,在离线测试中显示出优于基线方法的性能,并在在线A/B测试中实现了0.616%的应用使用时长提升。 AI

影响 通过改进跨阶段融合和偏好对齐来增强推荐系统性能,可能带来更具吸引力的用户体验。

    UniRec:跨阶段多任务融合与偏好对齐用于级联推荐系统

    Industrial recommender systems use cascaded stages with different objectives, feature spaces, and latency constraints. Optimizing pre-ranking and ranking separately can create cross-stage inconsistency: upstream models may filter out items preferred by downstream rankers, and ind…
