用粘性手套探索：通过选项模板进行专家干预的强化学习
Exploring with Sticky Mittens: Reinforcement Learning with Expert Interventions via Option Templates
摘要：
具有稀疏奖励的长时间机器人学习任务对当前的强化学习算法提出了重大挑战。使人类能够学习具有挑战性的控制任务的一个关键特征是，他们经常接受专家干预，使他们能够在掌握低级别控制动作之前理解任务的高级结构。我们提出了一个利用专家干预来解决长期强化学习任务的框架。我们考虑\emph{option templates}，这是一种编码潜在选项的规范，可以使用强化学习进行训练。我们制定专家干预，允许代理执行选项模板之前，学习实现。这使他们能够使用一个选项，然后再投入昂贵的资源来学习it.We评估我们的方法上三个具有挑战性的强化学习问题，表明它优于国家的最先进的方法两个数量级。培训代理的视频和我们的代码可以在https://sites.google.com/view/stickymittens上找到
英文摘要：
Long horizon robot learning tasks with sparse rewards pose a significant challenge for current reinforcement learning algorithms. A key feature enabling humans to learn challenging control tasks is that they often receive expert intervention that enables them to understand the high-level structure of the task before mastering low-level control actions. We propose a framework for leveraging expert intervention to solve long-horizon reinforcement learning tasks. We consider \emph{option templates}, which are specifications encoding a potential option that can be trained using reinforcement learning. We formulate expert intervention as allowing the agent to execute option templates before learning an implementation. This enables them to use an option, before committing costly resources to learning it. We evaluate our approach on three challenging reinforcement learning problems, showing that it outperforms state-of-the-art approaches by two orders of magnitude.
