SPAR框架通过改进SID构建来增强个性化推荐

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-20 09:17

研究人员开发了SPAR，一个用于个性化推荐系统的新框架，它改进了分步个性化和语义ID（SIDs）的构建。SPAR的PATH解码器将来自长期用户记忆的与前缀相关的证据与近期行为和上下文相结合，以指导每个token的决策。此外，其RQ-PIB模块在保持语义结构的同时，平衡了跨候选分支的历史交互负载。在优酷生产数据上的在线A/B测试显示，SPAR将用户平均观看时长提高了3.95%，播放转化率提高了3.38%，证明了更可靠的层次化解码和增强的用户参与度。 AI

影响增强了个性化推荐系统，可能提高了优酷等平台的用户参与度和内容发现。

SPAR: Stepwise Personalized Autoregressive Recommendation with Prefix-Balanced Semantic IDs

Semantic ID (SID)-based generative recommendation retrieves items through successive token-level decisions, making personalization at each decoding step essential. However, existing methods insufficiently account for prefix-dependent user evidence and imbalanced historical intera…
