Preference-Drift-Aware Subsequence Learning and Hierarchical Context Fusion for Long-Sequence Generative Recommendation

Fei Li, Qingyun Gao, Jianzhe Zhao +5

Long-sequence generative recommendation methods autoregressively model the user's interaction sequence to generate the next-item representation. Existing methods generally fall int…

Learning Preference Adaptation for Large Language Model Personalization via Verbal Reinforcement Learning

Yuting Liu, Wei Wu, Jianzhe Zhao +1

Natural language user preferences provide an interpretable interface for LLM personalization. However, universal preference summaries often contain information irrelevant to a part…

PCTD: Preference-Guided Counterfactual Task Decomposition for Agent Tool Retrieval

Chu Zhao, Lei Tang, Minghang Li +5

Task decomposition aims to transform ambiguous instructions into executable atomic subtasks, thereby guiding high-precision tool retrieval. However, our analysis reveals that direc…

Causal Direct Preference Optimization for Distributionally Robust Generative Recommendation

Chu Zhao, Enneng Yang, Jianzhe Zhao +1

Direct Preference Optimization (DPO) guides large language models (LLMs) to generate recommendations aligned with user historical behavior distributions by minimizing preference al…

ECHO: Entropy-Confidence Hybrid Optimization for Test-Time Reinforcement Learning

Chu Zhao, Enneng Yang, Yuting Liu +2

Test-time reinforcement learning generates multiple candidate answers via repeated rollouts and performs online updates using pseudo-labels constructed by majority voting. To reduc…

Tail-Aware Data Augmentation for Long-Tail Sequential Recommendation

Yizhou Dang, Zhifu Wei, Minhan Huang +4

Sequential recommendation (SR) learns user preferences based on their historical interaction sequences and provides personalized suggestions. In real-world scenarios, most users ca…
