CASP算法改进了两阶段推荐系统的离线策略选择

研究人员推出了一种用于两阶段推荐系统策略选择的新方法CASP(Coupled Action-Set Pessimism,耦合动作集悲观法)。该方法解决了初始物品生成器改变会同时改变估计策略值和支持该估计的数据的挑战。CASP结合了双重稳健值估计和弱数据支持的惩罚项,旨在通过考虑数据的可信度来选择更可靠的策略。 AI

影响 引入了一种新的两阶段推荐系统离线选择方法,通过考虑数据支持来潜在地提高推荐准确性。

排序理由 这是一篇详细介绍推荐系统新方法的学术论文。

    Two-stage recommender systems first choose a candidate generator and then rank items within the generated set. Because the generator decides which items are available to the ranker, changing the generator changes both the policy value and the data support used to estimate that va…
