研究人员开发了一个可扩展的图神经网络（GNN）系统，用于处理大型社交图的好友推荐，解决了海量数据集的挑战。该系统采用了多哈希ID嵌入，显著减小了嵌入表的大小，并结合了时序邻居采样和优化的数据结构，实现了高效处理。在线A/B测试表明，与基线系统相比，推荐的好友添加数增加了16%，唯一添加好友的用户数增加了11.5%。 AI

影响这项研究为推荐系统提供了一个可扩展的解决方案，有望提高社交平台的用户参与度。

本文如何被排名

Signal score: 6 / 100; Composite score across the factors below. Higher = stronger signal that this story matters right now.
Newsworthiness bucket: Tool; 学术论文，详细介绍了新颖的技术方法及其评估。[lever_c_demoted from research: ic=1 ai=1.0]
Source corroboration: Single-source cluster; Only one publisher covered this so far. Single-source stories can still rank when the publisher is high-authority, but they lack cross-source corroboration.
Topics: paper, infra; Editorial topic classification. Feeds into how the story surfaces on /topic/<slug> hub pages and into the per-entity coverage mix.
AI-industry relevance: High; Clearly on-topic for AI-industry coverage.
Story freshness: Same-day; Cluster formed today. Ranking reflects the current source set at time of score.

为好友推荐扩展图神经网络：多哈希用户嵌入与时序邻居采样

Friend recommendation is inherently graph-structured: the relevance of a potential connection depends on multi-hop social context rather than user attributes alone. However, deploying message-passing GNNs on a production-scale social graph with hundreds of millions of users and t…
