Study deconstructs actor-critic algorithms, finding bounded distributions more robust

A new study published on arXiv analyzes over 33,000 experiments to deconstruct actor-critic algorithms in reinforcement learning. The research identifies that common default configurations, such as Gaussian action distributions with pathwise gradient estimators, are among the least reliable. Conversely, bounded distributions paired with adaptive update schedules demonstrated robustness across various settings, offering practical guidance for practitioners applying these methods to real-world control tasks.
