AI总结:

CADENT通过结合战略自动机知识与战术策略知识,提出经验门控信任机制,实现强化学习中样本高效的知识迁移。

摘要:

迁移学习旨在减少深度强化学习(RL)的高样本复杂性,但现有方法在源环境和目标环境之间域偏移时表现不佳。策略蒸馏提供了强大的战术指导,但无法转移长期的战略知识,而基于自动机的方法捕捉了任务结构,但缺乏精细的动作指导。本文介绍了Context-Aware Distillation with Experience-gated Transfer(CADENT),一种将战略自动机知识与战术策略层面知识统一到一致指导信号的框架。CADENT的关键创新是一个经验门控信任机制,能够在状态-动作层面动态权衡教师指导与学生自身经验,从而适应目标领域特定需求。在具有挑战性的环境中,从稀疏奖励网格世界到连续控制任务,CADENT在样本效率上比基线方法提高40-60%,同时保持优越的渐进行为性能,建立了一种稳健的适应性知识迁移方法。

英文摘要:

Transfer learning promises to reduce the high sample complexity of deep reinforcement learning (RL), yet existing methods struggle with domain shift between source and target environments. Policy distillation provides powerful tactical guidance but fails to transfer long-term strategic knowledge, while automaton-based methods capture task structure but lack fine-grained action guidance. This paper introduces Context-Aware Distillation with Experience-gated Transfer (CADENT), a framework that unifies strategic automaton-based knowledge with tactical policy-level knowledge into a coherent guidance signal. CADENT's key innovation is an experience-gated trust mechanism that dynamically weighs teacher guidance against the student's own experience at the state-action level, enabling graceful adaptation to target domain specifics. Across challenging environments, from sparse-reward grid worlds to continuous control tasks, CADENT achieves 40-60\% better sample efficiency than baselines while maintaining superior asymptotic performance, establishing a robust approach for adaptive knowledge transfer in RL.
