摘要:

尽管深度强化学习算法取得了进步,但开发有效的探索策略仍然是一个悬而未决的问题。大多数现有的探索策略或者基于简单的算法,或者需要环境的模型,或者训练额外的深度神经网络来生成增强路径。在本文中,一个革命性的算法,称为策略增强,介绍。策略增强是基于一个新开发的归纳矩阵完成方法。该算法增加了未探索的状态动作对的值,帮助代理采取行动,这将导致高价值的回报,而代理是在早期的情节。使用高价值的推出来训练深度强化学习算法可以加快深度强化学习算法的收敛速度。我们的实验表明,优越的性能的政策增强。代码可以在https://github.com/arashmahyari/PolicyAugmentation上找到。

英文摘要:

Despite advancements in deep reinforcement learning algorithms, developing an effective exploration strategy is still an open problem. Most existing exploration strategies either are based on simple heuristics, or require the model of the environment, or train additional deep neural networks to generate imagination-augmented paths. In this paper, a revolutionary algorithm, called Policy Augmentation, is introduced. Policy Augmentation is based on a newly developed inductive matrix completion method. The proposed algorithm augments the values of unexplored state-action pairs, helping the agent take actions that will result in high-value returns while the agent is in the early episodes. Training deep reinforcement learning algorithms with high-value rollouts leads to the faster convergence of deep reinforcement learning algorithms. Our experiments show the superior performance of Policy Augmentation. The code can be found at: https://github.com/arashmahyari/PolicyAugmentation.
