Cross-Country Code-Mixing for Generative Recommendation

Yuan Gao, Hao Deng, Haibo Xing +5

Cross-country recommendation on modern e-commerce platforms is typically deployed with disjoint user and item ID spaces across markets, removing the shared anchors that conventiona…

Astar: Learning to Propose Evolution Directions for Self-Evolving Industrial AI Systems

Jinxin Hu, Hao Deng, Haibo Xing +12

Modern AI systems advance through continuous iteration: a loop of proposing evolution directions, implementing code, training, and evaluation. While the latter three stages are inc…

EvoRec: Self Evolving Agentic Recommender Systems

Lingyu Mu, Hao Deng, Haibo Xing +3

Optimizing modern recommender systems still relies heavily on engineers iterating by hand, which is slow and bounded by individual expertise. LLM-based agents open a path toward au…

LWGR: Lagrangian-Constrained Personalized World Knowledge for Generative Recommendation

Lingyu Mu, Hao Deng, Haibo Xing +7

Recent progress in large language model (LLM) based generative recommendation (GR) shows that leveraging LLM world knowledge can substantially improve performance. However, existin…

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…

Learning to Reflect and Correct: Towards Better Decoding Trajectories for Large-Scale Generative Recommendation

Haibo Xing, Hao Deng, Lingyu Mu +4

Generative Recommendation (GR) has become a promising paradigm for large-scale recommendation systems. However, existing GR models typically perform single-pass decoding without ex…

Masked Diffusion Generative Recommendation

Lingyu Mu, Hao Deng, Haibo Xing +4

Generative recommendation (GR) typically first quantizes continuous item embeddings into multi-level semantic IDs (SIDs), and then generates the next item via autoregressive decodi…

Synergistic Integration and Discrepancy Resolution of Contextualized Knowledge for Personalized Recommendation

Lingyu Mu, Hao Deng, Haibo Xing +7

The integration of large language models (LLMs) into recommendation systems has revealed promising potential through their capacity to extract world knowledge for enhanced reasonin…
