Bellman-Taylor Score Decoding for Markov Decision Processes with State-Dependent Feasible Action Sets
Researchers have introduced a new framework called Bellman-Taylor score decoding to address challenges in applying deep reinforcement learning to Markov decision processes with complex, state-dependent actions. This method maps policy learning into a Euclidean score space, allowing standard DRL algorithms to be used while enforcing feasibility through an action decoder. The approach has demonstrated near-optimal performance in small-scale tests and significant improvements over existing methods in larger systems, particularly when applied to queueing network control problems.
