HD-Rec框架通过分层量化增强跨域推荐

研究人员推出了一种新颖的生成式推荐框架HD-Rec,旨在解决跨域推荐的复杂性。该系统利用分层域感知量化器创建语义标识符,结合共享的粗粒度码本和自适应的细粒度码本。此外,它还包含一个域自适应稀疏专家混合模块用于动态专家选择,以及一个一致性目标来优化多令牌项表示。在公开基准上的实验表明,HD-Rec的性能优于现有的顺序、生成式和跨域推荐方法。 AI

影响 这项研究可能带来跨不同平台和服务的更准确、更个性化的推荐。

    面向生成式跨域推荐的领域自适应稀疏路由分层量化

    Generative Recommendation (GenRec) represents a promising paradigm that achieves remarkable empirical success by encoding items as compact Semantic IDs (SIDs) and modeling user behavior via next-token prediction across diverse recommendation scenarios. Extending this paradigm to …
