This paper addresses a critical challenge in real-world reinforcement learning: how to effectively utilize potentially suboptimal human interventions to accelerate learning without being overly constrained by them. The proposed SiLRI algorithm offers a novel approach by formulating the problem as a constrained RL optimization, using a state-wise Lagrange multiplier to account for the uncertainty of human interventions. The results demonstrate significant improvements in learning speed and success rates compared to existing methods, highlighting the practical value of the approach for robotic manipulation.
