Communication Policy Evolution for Proactive LLM Agents

Xinbei Ma, Jiyang Qiu, Yao Yao +10

LLM agents have rapidly evolved into autonomous systems, yet a persistent information gap remains between users and agents: communication is costly, while users' identical preferen…

Retrospective Progress-Aware Self-Refinement for LLM Agent Training

Xinbei Ma, Congmin Zheng, Jiyang Qiu +10

LLM-based agents trained with reinforcement learning optimize step-wise action prediction but lack metacognitive awareness of task progress, inducing a gap that hinders long-horizo…

Holder Policy Optimisation

Yuxiang Chen, Dingli Liang, Yihang Chen +8

Group Relative Policy Optimisation (GRPO) enhances large language models by estimating advantages across a group of sampled trajectories. However, mapping these trajectory-level ad…

Skills on the Fly: Test-Time Adaptive Skill Synthesis for LLM Agents

Jingxing Wang, Chenyu Zhou, Zhihui Fu +4

Additional test-time compute can give LLM agents access to more past experience, yet expanding the context or adding rollouts does not necessarily yield greater agent capability. W…
