摘要:

从视觉观察中学习解决复杂的操作任务是现实世界机器人学习的主要挑战。尽管深度强化学习算法最近在这方面取得了令人印象深刻的结果,但它们仍然需要大量耗时的试错迭代。在这项工作中,我们认为有前途的替代范式的交互式学习中,一个人类教师提供反馈的政策在执行过程中,而不是模仿学习,使用预先收集的数据集完美的演示。我们提出的CEILing(纠正和评价的互动学习)框架结合了纠正和评价的反馈,从教师训练的随机政策,在异步的方式,并采用了一个专门的机制来权衡人类的更正与机器人自己的经验。我们在广泛的模拟和真实世界的实验中展示了我们的框架所获得的结果,以证明CEILing可以在不到一个小时的真实世界训练中直接从原始图像有效地解决复杂的机器人操作任务。

英文摘要:

Learning to solve complex manipulation tasks from visual observations is a dominant challenge for real-world robot learning. Although deep reinforcement learning algorithms have recently demonstrated impressive results in this context, they still require an impractical amount of time-consuming trial-and-error iterations. In this work, we consider the promising alternative paradigm of interactive learning in which a human teacher provides feedback to the policy during execution, as opposed to imitation learning where a pre-collected dataset of perfect demonstrations is used. Our proposed CEILing (Corrective and Evaluative Interactive Learning) framework combines both corrective and evaluative feedback from the teacher to train a stochastic policy in an asynchronous manner, and employs a dedicated mechanism to trade off human corrections with the robot's own experience. We present results obtained with our framework in extensive simulation and real-world experiments to demonstrate that CEILing can effectively solve complex robot manipulation tasks directly from raw images in less than one hour of real-world training.
