摘要:

近年来,强化学习(RL)在真实世界应用中的进展依赖于大规模准确模拟系统的能力。然而,流体动力学系统等领域展现出复杂的动态现象,难以在高积分速率下进行模拟,这限制了现代深度RL算法在通常昂贵或安全关键的硬件上的直接应用。在本工作中,我们引入了“Box o Flows”,一种新颖的台式实验控制系统,用于在动态真实世界场景中系统评估RL算法。我们描述了Box o Flows的关键组件,并通过一系列实验展示了最先进的无模型RL算法如何通过简单的奖励规范合成各种复杂行为。此外,我们探讨了离线RL在通过重用过去经验进行数据高效假设检验中的作用。我们相信,从这项初步研究中获得的见解以及像Box o Flows这样的系统的可用性,为开发能够普遍应用于复杂动态系统的系统性RL算法铺平了道路。补充材料和实验视频可在https://sites.google.com/view/box-o-flows/home获取。

英文摘要:

Recent advances in real-world applications of reinforcement learning (RL) have relied on the ability to accurately simulate systems at scale. However, domains such as fluid dynamical systems exhibit complex dynamic phenomena that are hard to simulate at high integration rates, limiting the direct application of modern deep RL algorithms to often expensive or safety critical hardware. In this work, we introduce "Box o Flows", a novel benchtop experimental control system for systematically evaluating RL algorithms in dynamic real-world scenarios. We describe the key components of the Box o Flows, and through a series of experiments demonstrate how state-of-the-art model-free RL algorithms can synthesize a variety of complex behaviors via simple reward specifications. Furthermore, we explore the role of offline RL in data-efficient hypothesis testing by reusing past experiences. We believe that the insights gained from this preliminary study and the availability of systems like the Box o Flows support the way forward for developing systematic RL algorithms that can be generally applied to complex, dynamical systems.
