Towards Efficient Reasoning in LLM-Based Recommender Systems via Model Merging

Linh Dieu Le, Tong Chen, Shazia Sadiq +3

Large language model-based recommender systems are increasingly adopting slow-thinking models that generate step-by-step reasoning before making predictions, often achieving higher…

ASPIRE: Make Spectral Graph Collaborative Filtering Great Again via Adaptive Filter Learning

Yunhang He, Cong Xu, Zhangchi Zhu +2

Graph filter design is central to spectral collaborative filtering, yet most existing methods rely on manually tuned hyperparameters rather than fully learnable filters. We show th…

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…

When Graph Contrastive Learning Backfires: Spectral Vulnerability and Defense in Recommendation

Zongwei Wang, Min Gao, Junliang Yu +3

Graph Contrastive Learning (GCL) has demonstrated substantial promise in enhancing the robustness and generalization of recommender systems, particularly by enabling models to leve…
