Researchers have developed a new method to stabilize the training of Deep Q-learning (DQL) algorithms, which are known for their instability. The study provides a unified analysis of instability from three perspectives: bias in Bellman bootstrapping, sensitivity of greedy action selection, and parameter dynamics with aggressive data reuse. The proposed stabilization principles, including controlled bootstrapping and ensemble quantile estimation, have demonstrated competitive performance and improved training stability in experiments on Atari-100K and Procgen environments.
