Repurposing Synthetic Data for Fine-grained Search Agent Supervision

arXiv — cs.CLWednesday, October 29, 2025 at 4:00:00 AM
A recent study highlights the limitations of current training methods for LLM-based search agents, particularly the Group Relative Policy Optimization (GRPO) approach, which overlooks valuable entity information in synthetic data. This oversight affects the agents' ability to learn from near-miss samples that could enhance their reasoning capabilities. Understanding and addressing these limitations is crucial for improving the effectiveness of search agents in handling complex tasks, ultimately leading to more accurate and efficient outcomes.
