Fisher-BRC is an actor critic algorithm for offline reinforcement learning that encourages the learned policy to stay close to the data, namely parameterizing the critic as the log-behavior-policy, which generated the offline dataset, plus a state-action value offset term, which can be learned using a neural network. Behavior regularization then corresponds to an appropriate regularizer on the offset term. A gradient penalty regularizer is used for the offset term, which is equivalent to Fisher divergence regularization, suggesting connections to the score matching and generative energy-based model literature.

Papers per year the archive tags with this method, by the paper's archive date (1 dated). Bars are counts, not a trend claim.

Components: the archive holds no method-to-method composition, so PwC's Components table cannot be rebuilt; the Papers list carries no Results column for the same reason (the archive does not join its leaderboard rows to method tags).
