摘要:

鉴于深度强化学习(DRL)在推荐系统研究中的出现以及近年来取得的一些丰硕成果,本文旨在对深度强化学习在推荐系统中的最新发展趋势进行及时而全面的综述。我们首先介绍了在推荐系统中应用DRL的动机。然后,我们提供了一个分类目前基于DRL推荐系统和现有的方法的总结。我们讨论新出现的主题和开放的问题,并提供我们对推进该领域的观点。本调查作为学术界和工业界读者对这一主题的介绍材料,并确定了进一步研究的重要机会。

英文摘要:

In light of the emergence of deep reinforcement learning (DRL) in recommender systems research and several fruitful results in recent years, this survey aims to provide a timely and comprehensive overview of the recent trends of deep reinforcement learning in recommender systems. We start with the motivation of applying DRL in recommender systems. Then, we provide a taxonomy of current DRL-based recommender systems and a summary of existing methods. We discuss emerging topics and open issues, and provide our perspective on advancing the domain. This survey serves as introductory material for readers from academia and industry into the topic and identifies notable opportunities for further research.
