English(EN) PFA: Attention Can Be Progressively Focused in Long-Sequence Generative Recommendation

新的PFA框架提高了生成推荐的效率

研究人员推出了一种名为渐进式聚焦注意力(PFA)的新框架,旨在提高生成推荐系统在处理长用户行为序列时的效率。PFA通过渐进式聚焦关键历史标记来解决自回归束搜索过程中全注意力机制引起的显著推理延迟问题。该系统利用了对注意力模式的观察,特别是渐进式聚焦和跨步排名一致性,以在保留基本语义的同时减少计算和内存开销。在电子商务平台上进行的实验和在线A/B测试表明,PFA能够以低推理延迟带来显著的业务收益。 AI

影响 提高了处理长用户历史记录的生成推荐系统的效率,可能降低平台的延迟和成本。

    PFA:长序列生成式推荐中的注意力可渐进式聚焦

    Long user behavioral sequences improve the performance of generative recommendation (GR), but computing full attention over long histories during autoregressive beam search decoding incurs substantial online inference latency. To accelerate long-sequence decoding, existing approa…
