WebFeb 7, 2024 · Safe Wasserstein Constrained Deep Q-Learning. This paper presents a distributionally robust Q-Learning algorithm (DrQ) which leverages Wasserstein ambiguity sets to provide probabilistic out-of-sample safety guarantees during online learning. First, we follow past work by separating the constraint functions from the principal objective to ... WebDespite the complexity, we show that the resulting distributionally robust Q -learning algorithm asymptotically converges to optimal worst-case policy, thus making it robust to future environment changes. Simulation results further demonstrate its strong empirical robustness. Cite this Paper BibTeX
WebJul 13, 1999 · Q-learning algorithm for classical Markov decision processes. The algorithm is shown to converge with probability one to the desired solution. The proof technique is an adaptation of the o.d.e. approach for the analysis of stochastic approximation algorithms, with most of the work involved WebQ(s0;b) : The optimal policy ˇ (s) = argmax a2AQ(s;a). There-fore, policy learning in RL environments can be achieved if we can learn a good estimate of Q. 2.2 Distributionally Robust Formulation We consider a DR-RL setting, where both transition prob-abilities and rewards are perturbed based on the KL diver-gence D KL(PkQ) := R log dP dQ P(d ...
