Researchers have developed a new statistical analysis for Deep Q-Networks (DQN) that accounts for temporal dependence in training data. This approach models minibatches as $\tau$-mixing, moving beyond the typical assumption of independence. The findings indicate that temporal dependence can reduce the statistical rate of learning by introducing a dimensionality penalty, effectively lowering the sample size. AI
