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…

HARDE: Optimizing Agent Harnesses for Runtime Risk Detection and Execution Control

Zhuo Liu, Moxin Li, Zhixin Ma +3

Large language model (LLM) agents are vulnerable to safety risks such as injected malicious instructions or misleading information, motivating runtime defenses that prevent unsafe…

CAST: Game Solvers as Turn-Level Teachers for LLM Agents

Yu Wang, Yi-Kai Zhang, Wentao Shi +8

Training large language models (LLMs) to act in long-horizon games is a promising step toward generalist decision-making, yet reinforcement learning with verifiable rewards (RLVR)…

Look Before You Leap: Autonomous Exploration for LLM Agents

Ziang Ye, Wentao Shi, Yuxin Liu +6

Large language model based agents often fail in unfamiliar environments due to premature exploitation: a tendency to act on prior knowledge before acquiring sufficient environment-…

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…

AJ-Bench: Benchmarking Agent-as-a-Judge for Environment-Aware Evaluation

Wentao Shi, Yu Wang, Yuyang Zhao +8

As reinforcement learning continues to scale the training of large language model-based agents, reliably verifying agent behaviors in complex environments has become increasingly c…
