Abstract
The Double Actor Critic (DAC) reinforcement-learning algorithm affords stable policy improvement and aggressive neural-net optimization without catastrophic overfitting of the policy. DAC trains models using an arbitrary history of data in both offline and online learning and can be used to smoothly improve on an existing policy learned or defined by some other means. Finally, DAC can optimize reinforcement learning problems with discrete and continuous action spaces.
