GRACE: Generative Recommender Acceleration Engine for Real-Time Ads Retrieval

Zhou Fang, Yuhang Huang, Ang Zhang +12

Productionizing generative recommenders for high-volume, real-time ads retrieval creates two serving challenges: eligibility, ensuring that each generated ad is eligible for the re…

Diffusion-GR2: Diffusion Generative Reasoning Re-ranker

Zhuoxuan Zhang, Kangqi Ni, Yuhang Chen +12

Generative reasoning re-rankers achieve strong recommendation accuracy by emitting a chain-of-thought before re-ordering a candidate list, but they are slow at inference: an autore…

Self-Guided Test-Time Training for Long-Context LLMs

Xinyu Zhu, Zhe Xu, Xiaohan Wei +10

Long-context processing has become increasingly important for large language models (LLMs), but simply extending the context window does not guarantee effective utilization of long…

SCOReD: Student-Aware CoT Optimization for Recommendation Distillation

Haz Sameen Shahgir, Yufei Li, Xiaohan Wei +8

Chain-of-thought (CoT) distillation in the recommendation domain is a necessary precursor to RL training, but raw teacher traces are ill-suited to this task. Large teachers approac…

GR2 Technical Report

Yufei Li, Zaiwei Zhang, Mingfu Liang +67

Industrial recommendation systems serve billions of users through a multi-stage funnel -- retrieval, early-stage ranking, and re-ranking -- where the final re-ranking step dispropo…

End-to-End Dynamic Sparsity for Resource-Adaptive LLM Inference

Yuhang Chen, Jinhao Duan, Ruichen Zhang +11

Large Language Models (LLMs) inference is typically deployed under a static resource assumption, where models execute a fixed computational graph regardless of the runtime environm…

Bifocal Diffusion Language Models: Asymmetric Bidirectional Context for Parallel Generation

Yuhang Chen, Xianfeng Wu, Jinhao Duan +11

Discrete diffusion language models (dLLMs) recover masked tokens in parallel, offering significant speedups over autoregressive (AR) generation. However, such promising frameworks…

Learning Evidence Highlighting for Frozen LLMs

Shaoang Li, Yanhang Shi, Yufei Li +10

Large Language Models (LLMs) can reason well, yet often miss decisive evidence when it is buried in long, noisy contexts. We introduce HiLight, an Evidence Emphasis framework that…

SOLARIS: Speculative Offloading of Latent-bAsed Representation for Inference Scaling

Zikun Liu, Liang Luo, Qianru Li +31

Recent advances in recommendation scaling laws have led to foundation models of unprecedented complexity. While these models offer superior performance, their computational demands…

Haystack Engineering: Context Engineering for Heterogeneous and Agentic Long-Context Evaluation

Mufei Li, Dongqi Fu, Limei Wang +10

Modern long-context large language models (LLMs) perform well on synthetic "needle-in-a-haystack" (NIAH) benchmarks, but such tests overlook how noisy contexts arise from biased re…

Hierarchical Structured Neural Network: Efficient Retrieval Scaling for Large Scale Recommendation

Kaushik Rangadurai, Siyang Yuan, Minhui Huang +12

Retrieval, the initial stage of a recommendation system, is tasked with down-selecting items from a pool of tens of millions of candidates to a few thousands. Embedding Based Retri…
