SAC algorithm
- 参数:
model (parl.Model) – forward network of actor and critic.
gamma (float) – discounted factor for reward computation
tau (float) – decay coefficient when updating the weights of self.target_model with self.model
alpha (float) – temperature parameter determines the relative importance of the entropy against the reward
actor_lr (float) – learning rate of the actor model
critic_lr (float) – learning rate of the critic model
