Rethinking Recommendation Paradigms: From Pipelines to Agentic Recommender Systems

Jinxin Hu, Hao Deng, Lingyu Mu +4

Large-scale industrial recommenders typically use a fixed multi-stage pipeline (recall, ranking, re-ranking) and have progressed from collaborative filtering to deep and large pre-…

AgenticRS-Architecture: System Design for Agentic Recommender Systems

Hao Zhang, Jinxin Hu, Hao Deng +4

AutoModel is an agent based architecture for the full lifecycle of industrial recommender systems. Instead of a fixed recall and ranking pipeline, AutoModel organizes recommendatio…
