Soft Actor-Critic: Off-Policy Maximum Entropy Deep Reinforcement Learning with a Stochastic Actor

Haarnoja, Tuomas, Zhou, Aurick, Abbeel, Pieter et al.

Understand

Model-free deep reinforcement learning (RL) algorithms have been demonstrated on a range of challenging decision making and control tasks.

  • However, these methods typically suffer from two major challenges: very high sample complexity and brittle convergence properties, which necessitate meticulous hyperparameter tuning.
  • Both of these challenges severely limit the applicability of such methods to complex, real-world domains.
  • In this paper, we propose soft actor-critic, an off-policy actor-critic deep RL algorithm based on the maximum entropy reinforcement learning framework.
