Structuring and Tokenizing Distributed User Interest Context for Generative Recommendation

Ruizhong Qiu, Yinglong Xia, Dongqi Fu +6

Generative recommendation is an emerging paradigm that has shown promise in industrial recommendation systems, aiming to predict users' next interactions from their historical beha…

DAG-MoE: From Simple Mixture to Structural Aggregation in Mixture-of-Experts

Jiarui Feng, Hanqing Zeng, Karish Grover +11

Mixture-of-Experts (MoE) models have become a leading approach for decoupling parameter count from computational cost in large language models, yet effectively scaling MoE performa…

ReMix: Reinforcement routing for mixtures of LoRAs in LLM finetuning

Ruizhong Qiu, Hanqing Zeng, Yinglong Xia +15

Low-rank adapters (LoRAs) are a parameter-efficient finetuning technique that injects trainable low-rank matrices into pretrained models to adapt them to new tasks. Mixture-of-LoRA…

Retrieval Augmentation via User Interest Clustering

Hanjia Lyu, Hanqing Zeng, Yinglong Xia +2

Many existing industrial recommender systems are sensitive to the patterns of user-item engagement. Light users, who interact less frequently, correspond to a data sparsity problem…

Decoupling the Depth and Scope of Graph Neural Networks

Hanqing Zeng, Muhan Zhang, Yinglong Xia +6

State-of-the-art Graph Neural Networks (GNNs) have limited scalability with respect to the graph and model sizes. On large graphs, increasing the model depth often means exponentia…

Deep Graph Neural Networks with Shallow Subgraph Samplers

Hanqing Zeng, Muhan Zhang, Yinglong Xia +6

While Graph Neural Networks (GNNs) are powerful models for learning representations on graphs, most state-of-the-art models do not have significant accuracy gain beyond two to thre…
