摘要:

本文介绍了两种简单的技术,以改善离政策强化学习(RL)算法。首先,我们制定了一个随机的近点迭代的政策外RL。目标网络充当优化变量的角色,价值网络计算邻近算子。其次,我们利用两个价值函数通常采用的国家的最先进的政策外的算法,以提供一个改进的行动价值估计,通过引导有限的增加计算资源。此外,我们证明了显着的性能改善,在标准的连续控制RL基准的最先进的算法。

英文摘要:

This paper introduces two simple techniques to improve off-policy Reinforcement Learning (RL) algorithms. First, we formulate off-policy RL as a stochastic proximal point iteration. The target network plays the role of the variable of optimization and the value network computes the proximal operator. Second, we exploits the two value functions commonly employed in state-of-the-art off-policy algorithms to provide an improved action value estimate through bootstrapping with limited increase of computational resources. Further, we demonstrate significant performance improvement over state-of-the-art algorithms on standard continuous-control RL benchmarks.
