摘要:

近年来,强化学习(RL)已成为一个日益活跃的研究领域。虽然有许多算法可以让智能体有效地解决任务,但它们通常忽略了与手头任务相关的先前经验可能可用的可能性。对于许多实际应用,代理从头开始学习如何解决任务可能是不可行的,因为它通常是一个计算昂贵的过程;然而,可以利用以前的经验使这些问题在实践中易于处理。在本文中,我们提出了一个框架,利用现有的经验,通过学习可重用的选项。我们表明,在智能体学习解决少量问题的策略后,我们能够使用从这些策略生成的轨迹来学习可重用的选项,使智能体能够快速学习如何解决新的和相关的问题。

英文摘要:

Reinforcement learning (RL) has become an increasingly active area of research in recent years. Although there are many algorithms that allow an agent to solve tasks efficiently, they often ignore the possibility that prior experience related to the task at hand might be available. For many practical applications, it might be unfeasible for an agent to learn how to solve a task from scratch, given that it is generally a computationally expensive process; however, prior experience could be leveraged to make these problems tractable in practice. In this paper, we propose a framework for exploiting existing experience by learning reusable options. We show that after an agent learns policies for solving a small number of problems, we are able to use the trajectories generated from those policies to learn reusable options that allow an agent to quickly learn how to solve novel and related problems.
