English(EN) Timing-Aware Repurchase Prediction for Web-Scale E-Commerce: Survival Models for Multi-Surface Grocery Recommendation

新的生存模型增强了电子商务的再购预测能力

作者 PulseAugur 编辑部 · [1 个来源] · 2026-08-31 04:00

研究人员开发了一种新的方法，使用生存模型来预测电子商务中的客户再购行为，该模型直接估计再购发生的时间。该方法用一个模型取代了针对不同时间范围的多个二元分类器，显示出更高的效率和性能。研究还发现，在加速失效时间（AFT）模型系列中，校准质量和排名性能之间存在权衡，建议针对不同应用使用不同的模型。 AI

影响这项研究可能带来更准确、更高效的电子商务推荐系统。

面向网络规模电子商务的时序感知回购预测：用于多表面杂货推荐的生存模型

arXiv:2608.28393v1 Announce Type: cross Abstract: Repurchase recommenders in e-commerce are commonly framed as a binary question asking "will this customer buy this item within W days", a formulation that requires a separately trained model for every horizon of interest. We repla…
