学习和解决规则决策过程

Learning and Solving Regular Decision Processes

Eden Abadi, Ronen I. Brafman

摘要:

规则决策过程(RDPs)是最近引入的一种模型,它扩展了MDP与非马尔可夫动力学和奖励。非马尔可夫行为被限制为依赖于历史的正则性质。这些可以使用有限迹上的线性动态逻辑中的正则表达式或公式来指定。完全指定的RDP可以通过将其编译为适当的MDP来解决。从数据中学习RDP是一个具有挑战性的问题,尚未得到解决,我们在本文中集中。我们的方法依赖于一个新的表示RDPs使用Mealy机发出的分布和每个状态动作对的预期奖励。在此表示的基础上,我们将自动机学习技术与历史聚类相结合,学习这样一个Mealy机,并通过调整MCTS来解决它。

英文摘要:

Regular Decision Processes (RDPs) are a recently introduced model that extends MDPs with non-Markovian dynamics and rewards. The non-Markovian behavior is restricted to depend on regular properties of the history. These can be specified using regular expressions or formulas in linear dynamic logic over finite traces. Fully specified RDPs can be solved by compiling them into an appropriate MDP. Learning RDPs from data is a challenging problem that has yet to be addressed, on which we focus in this paper. Our approach rests on a new representation for RDPs using Mealy Machines that emit a distribution and an expected reward for each state-action pair. Building on this representation, we combine automata learning techniques with history clustering to learn such a Mealy machine and solve it by adapting MCTS to it. We empirically evaluate this approach, demonstrating its feasibility.
