When History Misleads: Asymmetric Margin Supervision for Instruction-Guided LLM Generative Recommendation

Ming Yin, Yuhan Yang, Chen Chen +10

In instruction-guided generative recommendation, LLM-based recommenders need to balance two goals: responding to the user's current request and aligning with the preferences in the…

EvoHarness-RL: Learning Runtime Harness Coordination for Self-Evolving Agents

Xuying Ning, Dongqi Fu, Tianxin Wei +17

Long-horizon LLM agents increasingly rely on external execution support to maintain state, track progress, recover from failures, and reuse experience across extended interactions.…

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…

Objective Shaping with Hard Negatives: Windowed Partial AUC Optimization for RL-based LLM Recommenders

Wentao Shi, Qifan Wang, Chen Chen +7

Reinforcement learning (RL) effectively optimizes Large Language Model (LLM)-based recommenders by contrasting positive and negative items. Empirically, training with beam-search n…

Bringing Reasoning to Generative Recommendation Through the Lens of Cascaded Ranking

Xinyu Lin, Pengyuan Liu, Wenjie Wang +5

Generative Recommendation (GR) has become a promising end-to-end approach with high FLOPS utilization for resource-efficient recommendation. Despite the effectiveness, we show that…
