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…

RCLRec: Reverse Curriculum Learning for Modeling Sparse Conversions in Generative Recommendation

Yulei Huang, Hao Deng, Haibo Xing +5

Conversion objectives in large-scale recommender systems are sparse, making them difficult to optimize. Generative recommendation (GR) partially alleviates data sparsity by organiz…

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…

REG4Rec: Reasoning-Enhanced Generative Model for Large-Scale Recommendation Systems

Haibo Xing, Hao Deng, Yucheng Mao +9

Sequential recommendation aims to predict a user's next action in large-scale recommender systems. While traditional methods often suffer from insufficient information interaction,…

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…
