English(EN) Decomposing Staleness in Recommender Systems: A Dual-Filter Framework for Supersession and Decay

Google Discover 部署新框架以对抗陈旧推荐

一个名为超期衰减过滤 (Supersession-Decay Filtering, SDF) 的新框架已被开发并部署到 Google Discover 中,以对抗陈旧的推荐。该系统通过两种主要机制解决陈旧性问题:超期(supersession),即新信息使旧内容过时;以及相关性衰减(relevance decay),即内容随时间自然失去价值。在线实验和为期两年的生产部署显示,用户报告的陈旧性问题显著减少,表明用户参与度有所提高,并且这是一种更强大的大规模内容相关性管理方法。 AI

影响 该框架提供了一个可扩展的解决方案,通过减少大规模推荐系统中的陈旧内容来提高用户参与度。

排序理由 该集群包含一篇研究论文,详细介绍了推荐系统的新框架,包括其在主要产品中的部署。
