From Understanding to Action: Feedback-Grounded Policy Discovery for Generative Recommendation

Zhi Chen, Minmao Wang, Xingchen Liu +8

The paper introduces a feedback‑driven framework that first extracts user intent and then discovers recommendation policies using outcome‑derived feedback, distilling this knowledg…

From Trajectories to Prefixes: Reusing Teacher Trajectories via Replayed Prefixes and Online Continuation

Yihan Wang, Zhong Guan, Haoran Sun +3

Small language models are attractive backbones for interactive agents, but direct distillation from strong teacher trajectories often turns rich multi-turn behavior into one-shot i…

Robust Contrastive Graph Clustering with Adaptive Local-Global Integration

Lei Zhang, Fubo Sun, Haipeng Yang +2

Graph clustering is essential in graph analysis for revealing structural patterns and node communities. Despite recent advances in self-supervised contrastive learning that have im…

GCIB: Graph Contrastive Information Bottleneck for Multi-Behavior Recommendation

Likang Wu, Zihao Chen, Jianxin Zhang +4

With the rapid emergence of multi-behavior learning in recommender systems, leveraging auxiliary user behaviors has proven effective for mitigating target-behavior data sparsity. Y…

Missing Old Logits in Asynchronous Agentic RL: Semantic Mismatch and Repair Methods for Off-Policy Correction

Zhong Guan, Yongjian Guo, Haoran Sun +5

Asynchronous reinforcement learning improves rollout throughput for large language model agents by decoupling sample generation from policy optimization, but it also introduces a c…

RL-VLA: A Flexible and Asynchronous Reinforcement Learning Framework for VLA Training

Haoran Sun, Yongjian Guo, Zhong Guan +13

Reinforcement learning (RL) has emerged as a critical paradigm for post-training Vision-Language-Action (VLA) models, enabling embodied agents to adapt and improve through environm…
