Based on this information, traders can assume further price movement and adjust this strategy accordingly. WebOffline Reinforcement Learning with Fisher Divergence Critic Regularization model literature (Lyu,2012;Bao et al.,2024), interpret- ing the critic values as the energy function of a Boltzmann distribution. We thus term our newly proposed actor critic algorithm Fisher-BRC (behavior regularized critic).
