Policy Consolidation for Continual Reinforcement Learning
Not on the map. Why?
Abstract (arXiv)
We propose a method for tackling catastrophic forgetting in deep reinforcement learning that is textitagnostic to the timescale of changes in the distribution of experiences, does not require knowledge of task boundaries, and can adapt in textitcontinuously changing environments. In our textitpolicy consolidation model, the policy network interacts with a cascade of hidden networks that simultaneously remember the agent's policy at a range of timescales and regularise the current policy by its own history, thereby improving its ability to learn without forgetting. We find that the model improves continual learning relative to baselines on a number of continuous control tasks in single-task, alternating two-task, and multi-agent competitive self-play settings.
