New mean-expansion layer accelerates reinforcement learning value sharing

Researchers have developed a new method called the mean-expansion layer to accelerate the learning of action-values in reinforcement learning algorithms like Q-learning. This layer efficiently shares value information across different actions within a single state, rather than updating each state-action pair independently. By learning a lower-norm representation of action-values, this approach has shown improved performance on Atari games, reduced value overestimation, and increased action gaps when integrated into deep Q-networks and implicit quantile networks.
