摘要:

强化学习(RL)的最新进展在许多模拟环境中已经超过了人类水平的性能。然而,现有的强化学习技术不能明确地将已知的领域特定的知识纳入学习过程。因此,智能体必须通过试错法独立地探索和学习领域知识,这消耗了时间和资源来做出有效的响应。因此,我们适应的深度确定性策略梯度(DDPG)算法,将顾问,它允许集成领域知识的形式预先学习的政策或预定义的关系,以提高代理的学习过程。我们在OpenAi Gym基准任务上的实验表明,通过顾问整合领域知识加快了学习,并提高了策略的最优性。

英文摘要:

Recent advances in Reinforcement Learning (RL) have surpassed human-level performance in many simulated environments. However, existing reinforcement learning techniques are incapable of explicitly incorporating already known domain-specific knowledge into the learning process. Therefore, the agents have to explore and learn the domain knowledge independently through a trial and error approach, which consumes both time and resources to make valid responses. Hence, we adapt the Deep Deterministic Policy Gradient (DDPG) algorithm to incorporate an adviser, which allows integrating domain knowledge in the form of pre-learned policies or pre-defined relationships to enhance the agent's learning process. Our experiments on OpenAi Gym benchmark tasks show that integrating domain knowledge through advisers expedites the learning and improves the policy towards better optima.
