Researchers have introduced Experience-Constrained Hierarchical Federated Reinforcement Learning (EC-HFRL) to address challenges in training large-scale UAV teams in hazardous environments. This new framework posits that in safety-critical scenarios with limited experience generation, learning performance is more dependent on experience reuse strategies and the identification of key gradient transition experiences rather than simply increasing learner participation. Empirical results suggest that minibatch size and the structure of the learning signal play a more significant role in effective replay exposure and overall performance than the level of intra-cluster participation.
