使用外部存储器的学习策略

Learning Policies with External Memory

Leonid Peshkin, Nicolas Meuleau, Leslie Kaelbling

摘要:

为了使智能体在部分可观察域中表现良好,通常需要行动依赖于观察的历史。在本文中,我们探讨了{ \it stigmergic}的方法,其中代理的行动包括设置和清除位在外部存储器的能力,和外部存储器包括作为输入到代理的一部分。在这种情况下,我们需要在一个高度非马尔可夫域中学习一个反应策略。我们探索两种算法:SARSA(λ),它在部分可观测域中取得了经验上的成功,以及VAPS,一种由Baird和Moore提出的新算法,在部分可观测域中具有收敛保证。我们比较了这两种算法的性能基准问题。

英文摘要:

In order for an agent to perform well in partially observable domains, it is usually necessary for actions to depend on the history of observations. In this paper, we explore a {\it stigmergic} approach, in which the agent's actions include the ability to set and clear bits in an external memory, and the external memory is included as part of the input to the agent. In this case, we need to learn a reactive policy in a highly non-Markovian domain. We explore two algorithms: SARSA(λ), which has had empirical success in partially observable domains, and VAPS, a new algorithm due to Baird and Moore, with convergence guarantees in partially observable domains. We compare the performance of these two algorithms on benchmark problems.
