Self-Distilled Reinforcement Learning for Co-Evolving Agentic Recommender Systems

Zongwei Wang, Min Gao, Hongzhi Yin +5

Large language model-empowered agentic recommender systems (ARS) reformulate recommendation as a multi-turn interaction between a recommender agent and a user agent, enabling itera…
