The proposed method, CERL, addresses the challenge of ensuring safety during reinforcement learning by introducing a new approach for constrained Markov decision processes. By leveraging Bayesian world models and pessimistic policy suggestions based on epistemic uncertainty, CERL achieves robustness against model inaccuracies and safe exploration during learning. In experiments, CERL outperforms state-of-the-art methods in terms of safety and optimality when solving CMDPs from image observations.

CERL is a new way to make sure machines learn safely online. It uses special models called Bayesian world models to help the machine think about what might happen if it makes certain choices. This helps the machine avoid making mistakes that could cause problems. CERL also suggests policies that are careful and considerate, which means the machine will explore and try new things in a way that doesn’t put anything at risk. In tests, CERL did better than other methods when it came to balancing safety with getting good results.
