状态空间中的交互式模仿学习

Interactive Imitation Learning in State-Space

Delft University of Technology(代尔夫特理工大学)

Snehal Jauhri, Carlos Celemin, Jens Kober

摘要:

模仿学习技术通过演示而不是手动工程来编程代理的行为。然而,它们受到现有示范数据质量的限制。交互式模仿学习技术可以提高学习的效率,因为它们涉及教师提供反馈,而代理执行其任务。在这项工作中,我们提出了一种新的交互式学习技术,在状态空间中使用人的反馈训练和提高代理的行为(而不是替代方法,使用反馈的动作空间)。我们的方法名为教学模仿政策的状态空间~(TIPS),使提供指导的代理方面的“改变其状态”,这往往是更直观的人类示威者。通过纠正反馈的持续改进,使用TIPS的非专家演示者训练的代理优于演示者和传统的模仿学习代理。

英文摘要:

Imitation Learning techniques enable programming the behavior of agents through demonstrations rather than manual engineering. However, they are limited by the quality of available demonstration data. Interactive Imitation Learning techniques can improve the efficacy of learning since they involve teachers providing feedback while the agent executes its task. In this work, we propose a novel Interactive Learning technique that uses human feedback in state-space to train and improve agent behavior (as opposed to alternative methods that use feedback in action-space). Our method titled Teaching Imitative Policies in State-space~(TIPS) enables providing guidance to the agent in terms of `changing its state' which is often more intuitive for a human demonstrator. Through continuous improvement via corrective feedback, agents trained by non-expert demonstrators using TIPS outperformed the demonstrator and conventional Imitation Learning agents.
