Query: Soft Actor-Critic Algorithms and Applications   Model-free deep reinforcement learning (RL) algorithms have been successfully
applied to a range of challenging sequential decision making and control tasks.
However, these methods typically suffer from two major challenges: high sample
complexity and brittleness to hyperparameters. Both of these challenges limit
the applicability of such methods to real-world domains. In this paper, we
describe Soft Actor-Critic (SAC), our recently introduced off-policy
actor-critic algorithm based on the maximum entropy RL framework. In this
framework, the actor aims to simultaneously maximize expected return and
entropy. That is, to succeed at the task while acting as randomly as possible.
We extend SAC to incorporate a number of modifications that accelerate training
and improve stability with respect to the hyperparameters, including a
constrained formulation that automatically tunes the temperature
hyperparameter. We systematically evaluate SAC on a range of benchmark tasks,
as well as real-world challenging tasks such as locomotion for a quadrupedal
robot and robotic manipulation with a dexterous hand. With these improvements,
SAC achieves state-of-the-art performance, outperforming prior on-policy and
off-policy methods in sample-efficiency and asymptotic performance.
Furthermore, we demonstrate that, in contrast to other off-policy algorithms,
our approach is very stable, achieving similar performance across different
random seeds. These results suggest that SAC is a promising candidate for
learning in real-world robotics tasks.
