Safe Exploration via Policy Priors

arXiv:2601.19612v3 Announce Type: replace-cross Abstract: Safe exploration is a key requirement for reinforcement learning (RL) agents to learn and adapt online, beyond controlled (e.g. simulated) environments. In this work, we tackle this challenge by utilizing suboptimal yet conservative policies (e.g., obtained from offline data or simulators) as priors. Our approach, SOOPER, uses probabilistic dynamics models to optimistically explore, yet pessimistically fall back to the conservative policy prior if needed. We prove that SOOPER guarantees safety throughout learning, and establish converge

Why this matters
Why now

The increasing push for real-world deployment of AI agents and RL models necessitates robust safety mechanisms to move beyond simulated environments.

Why it’s important

Safe exploration is a critical bottleneck for deploying autonomous reinforcement learning agents in sensitive or physical environments, directly impacting commercial viability and public trust.

What changes

The ability to formally guarantee safety during online learning opens up industrial and high-stakes applications for AI that were previously limited due to unpredictability.
