摘要

摘要:
时间差分算法(Temporal difference methods, TD)是一类模型无关的强化学习算法. 该算法拥有较低的方差和可以在线(On-line)学习的优点, 得到了广泛的应用. 但对于一种给定的TD算法, 往往只能通过调整步长参数或其他超参数来加速收敛, 这也就造成了加速TD算法收敛的方法匮乏. 针对此问题提出了一种利用蒙特卡洛算法(Monte Carlo methods, MC)来加速TD算法收敛的方法(Accelerate TD by MC, ATDMC). 该方法不仅可以适用于绝大部分的TD算法, 而且不需要改变在线学习的方式. 为了证明方法的有效性, 分别在同策略(On-policy)评估、异策略(Off-policy)评估和控制(Control)三个方面进行了实验. 实验结果表明ATDMC方法可以有效地加速各类TD算法.

Abstract:
Temporal difference methods (TD) methods are a class of model-free reinforcement learning methods. TD methods have been widely used, which have a low variance and can learn on-line. But for a given TD method, there is only one approach that adjusts the step size or other parameters to accelerate the convergence, which leads to a lack of methods to make it. To solve this problem, we introduce a method for accelerating TD methods based on Monte Carlo (MC) methods, which not only can be applied to most of the TD methods, but also do not need to change the way of on-line learning. In order to demonstrate the effectiveness of the method, experiments were carried out in the three aspects: the on-policy evaluation, off-policy evaluation and control. The experimental results show that the accelerate TD by MC (ATDMC) method can effectively accelerate TD methods.
