摘要:

本文讨论了学习抽象的问题,提高机器人规划性能,同时提供强有力的可靠性保证。尽管最先进的分层机器人规划算法允许机器人有效地计算用于实现用户期望的任务的长期运动计划,但是这些方法通常依赖于需要由专家手工设计的环境依赖的状态和动作抽象。我们提出了一种新的方法,引导整个层次规划过程。这使我们能够使用深度神经网络预测的关键区域自动计算新环境的抽象状态和动作,该深度神经网络具有自动生成的机器人特定架构。我们表明,学习的抽象可以使用一种新的多源双向分层机器人规划算法,是健全的和概率完整的。使用完整和非完整机器人对20种不同设置进行的广泛的经验评估表明:(a)我们学习的抽象提供了有效的多源层次规划所需的信息;以及(b)这种学习、抽象和规划的方法在训练过程中没有看到的测试环境的规划时间方面比最先进的基线高出近10倍。

英文摘要:

This paper addresses the problem of learning abstractions that boost robot planning performance while providing strong guarantees of reliability. Although state-of-the-art hierarchical robot planning algorithms allow robots to efficiently compute long-horizon motion plans for achieving user desired tasks, these methods typically rely upon environment-dependent state and action abstractions that need to be hand-designed by experts. We present a new approach for bootstrapping the entire hierarchical planning process. This allows us to compute abstract states and actions for new environments automatically using the critical regions predicted by a deep neural network with an auto-generated robot-specific architecture. We show that the learned abstractions can be used with a novel multi-source bi-directional hierarchical robot planning algorithm that is sound and probabilistically complete. An extensive empirical evaluation on twenty different settings using holonomic and non-holonomic robots shows that (a) our learned abstractions provide the information necessary for efficient multi-source hierarchical planning; and that (b) this approach of learning, abstractions, and planning outperforms state-of-the-art baselines by nearly a factor of ten in terms of planning time on test environments not seen during training.
