Fisher-BRC
Fisher-BRC is an algorithm used for offline reinforcement learning. It is based on actor-critic methods that encourage the learned policy to stay close to the data. The algorithm uses a neural network to learn the state-action value offset term, which can help regularize the policy changes. Actor-critic algorithm The actor-critic algorithm is a combination of two models - an actor and a critic. The actor is responsible for taking actions in the environment, and the critic is responsible for e
