用心理理论引导智能体在间歇监控下伪装合规,实现隐蔽目标。

Online Learning of Deceptive Policies under Intermittent Observation

  • 基于监督者预期构建可量化偏离证据的单一标量
  • 在线强化学习中动态平衡自利与合规,无需人工设计策略
  • 在无人船和无人机实机实验中验证高效且可解释

在监督控制场景中,自主系统并非持续被监控,而是以已知时间间隔进行间歇观测。本文研究欺骗问题:智能体在追求私有目标的同时,需在被观测时仍保持与监督者参考策略的表面合规性。受真实人类监督者行为启发,将问题置于心理理论(Theory of Mind)框架下,建模监督者信念与期望。通过提炼其期望生成一个校准后的标量——若当前发生观测,偏离证据的预期值。该标量融合了当前动作分布与参考分布的差异度,以及智能体对即将被观测的信念。将其作为状态相关权重注入在线强化学习的KL正则化策略改进步骤中,实现闭式更新,平滑权衡自我利益与合规性,避免手工或启发式策略。在海上无人船(ASV)与空中无人机(UAV)的真实硬件实时实验中,该基于心理理论的强化学习方法在线运行,获得高回报与成功率,且观测痕迹证据与监督者预期精确校准。

原文摘要 · Abstract (English)

In supervisory control settings, autonomous systems are not monitored continuously. Instead, monitoring often occurs at sporadic intervals within known bounds. We study the problem of deception, where an agent pursues a private objective while remaining plausibly compliant with a supervisor's reference policy when observations occur. Motivated by the behavior of real, human supervisors, we situate the problem within Theory of Mind: the representation of what an observer believes and expects to see. We show that Theory of Mind can be repurposed to steer online reinforcement learning (RL) toward such deceptive behavior. We model the supervisor's expectations and distill from them a single, calibrated scalar -- the expected evidence of deviation if an observation were to happen now. This scalar combines how unlike the reference and current action distributions appear, with the agent's belief that an observation is imminent. Injected as a state-dependent weight into a KL-regularized policy improvement step within an online RL loop, this scalar informs a closed-form update that smoothly trades off self-interest and compliance, thus sidestepping hand-crafted or heuristic policies. In real-world, real-time hardware experiments on marine (ASV) and aerial (UAV) navigation, our ToM-guided RL runs online, achieves high return and success with observed-trace evidence calibrated to the supervisor's expectations.
