New SADQ method enhances Q-value updates in Deep Q-Learning

Researchers have developed the Successor-state Aggregation Deep Q-Network (SADQ), a novel approach to enhance Q-value updates in Deep Q-Learning (DQN). SADQ addresses the issue of high variance in DQN updates caused by relying on next states from potentially suboptimal past policies. By explicitly modeling environment dynamics with a stochastic transition model and integrating successor-state distributions, SADQ aims to provide more stable and policy-aligned value updates. The method has demonstrated consistent outperformance over standard DQN variants in stability and learning efficiency across various reinforcement learning benchmarks and real-world control tasks.
