在分层操作模型中整合行动、规划和学习
Integrating Acting, Planning and Learning in Hierarchical Operational Models
摘要:
我们提出了新的规划和学习算法的RAE,细化代理引擎。RAE使用分层操作模型在动态变化的环境中执行任务。我们的规划程序,UPOM,在操作模型的空间中进行类似UCT的搜索,以便找到一个接近最佳的方法来用于手头的任务和背景。我们的学习策略获取,从在线表演经验和/或模拟规划结果,从决策上下文映射到方法实例,以及启发式功能,以指导UPOM。我们的实验结果表明,UPOM和我们的学习策略显着提高RAE的性能在四个测试领域使用两个不同的指标:效率和成功率。
英文摘要:
We present new planning and learning algorithms for RAE, the Refinement Acting Engine. RAE uses hierarchical operational models to perform tasks in dynamically changing environments. Our planning procedure, UPOM, does a UCT-like search in the space of operational models in order to find a near-optimal method to use for the task and context at hand. Our learning strategies acquire, from online acting experiences and/or simulated planning results, a mapping from decision contexts to method instances as well as a heuristic function to guide UPOM. Our experimental results show that UPOM and our learning strategies significantly improve RAE's performance in four test domains using two different metrics: efficiency and success ratio.
