SWIM 评估模型模拟会话动态,以改进推荐系统

研究人员推出了 SWIM(Step-Wise Integrated Measure),一种用于生成式重排推荐系统的新型列表级评估器。与传统独立评估列表的方法不同,SWIM 将用户行为建模为会话级别的生存过程,考虑了上下文依赖性和效用递减。该方法利用因果掩码 Transformer 有效估计续期概率和效用,满足工业延迟要求。实验表明,与现有基线相比,SWIM 显著提高了推荐参与度。 AI

影响 通过更好地模拟用户会话动态来增强推荐系统性能,有可能提高参与度指标。

    SWIM:生成式重排的会话监督列表评估的逐步集成度量

    Modern industrial recommender systems have increasingly adopted the Generator-Evaluator (G-E) framework for the re-ranking stage. Within this paradigm, the generator produces candidate item lists from a pool filtered by upstream retrieval and ranking modules, while the evaluator …
