A safe exploration approach to constrained Markov decision processes
Not on the map. Why?
Abstract (arXiv)
We consider discounted infinite-horizon constrained Markov decision processes (CMDPs), where the goal is to find an optimal policy that maximizes the expected cumulative reward while satisfying expected cumulative constraints. Motivated by the application of CMDPs in online learning for safety-critical systems, we focus on developing a model-free and simulator-free algorithm that ensures constraint satisfaction during learning. To this end, we employ the LB-SGD algorithm proposed in citeusmanova2022log, which utilizes an interior-point approach based on the log-barrier function of the CMDP. Under the commonly assumed conditions of relaxed Fisher non-degeneracy and bounded transfer error in policy parameterization, we establish the theoretical properties of the LB-SGD algorithm. In particular, unlike existing CMDP approaches that ensure policy feasibility only upon convergence, the LB-SGD algorithm guarantees feasibility throughout the learning process and converges to the varepsilon-optimal policy with a sample complexity of tildeO(varepsilon-6). Compared to the state-of-the-art policy gradient-based algorithm, C-NPG-PDA citebai2022achieving2, the LB-SGD algorithm requires an additional O(varepsilon-2) samples to ensure policy feasibility during learning with the same Fisher non-degenerate parameterization.
