Learn the Ropes, Then Trust the Wins: Self-imitation with Progressive Exploration for Agentic Reinforcement Learning

arXiv — cs.LGTuesday, December 9, 2025 at 5:00:00 AM
  • A new study introduces SPEAR, a self-imitation learning approach designed to enhance the exploration-exploitation balance in reinforcement learning for large language models (LLMs). This method aims to improve the stability of RL training by utilizing the agent's own experiences to guide policy entropy adjustments, addressing challenges associated with traditional exploration techniques.
  • The development of SPEAR is significant as it represents a step forward in training agentic LLMs, potentially leading to more efficient and effective learning processes. By focusing on self-imitation and progressive exploration, this approach could mitigate common pitfalls in reinforcement learning, such as instability and inefficiency.
  • This advancement aligns with ongoing efforts in the AI community to refine reinforcement learning techniques, particularly in enhancing reasoning capabilities and decision-making efficiency in LLMs. As various methods emerge to tackle issues like overthinking and interaction efficiency, the integration of self-imitation learning could play a crucial role in shaping future AI systems.
