CSPO: Constraint-Sensitive Policy Optimization for Safe Reinforcement Learning

arXiv:2606.14415v1 Announce Type: new Abstract: Safe reinforcement learning (Safe RL) aims to maximize expected return while satisfying safety constraints, typically modeled as Constrained Markov Decision Processes (CMDPs). While primal-dual methods scale well to deep RL, they often suffer from delayed constraint correction, leading to oscillatory behavior and prolonged safety violations. In this paper, we propose Constraint-Sensitive Policy Optimization (CSPO), a first-order primal-dual method that incorporates local constraint sensitivity into policy updates. CSPO augments the primal objecti

Why this matters
Why now

The increasing deployment of autonomous AI systems in real-world environments necessitates robust safety mechanisms to prevent undesirable outcomes.

Why it’s important

Ensuring AI systems operate safely and reliably is critical for their wide-scale adoption and public trust, especially in high-stakes applications.

What changes

This research introduces a more effective method for integrating safety constraints directly into AI policy optimization, reducing delays and instability common in previous approaches.
