摘要:

多智能体系统表现出复杂的行为,这些行为源于共享环境中多个智能体的交互。在这项工作中,我们感兴趣的是在多代理系统中控制一个代理,并成功地学习与其他代理有固定的政策。对其他代理(对手)的行为进行建模对于理解系统中代理的交互至关重要。通过利用无监督学习的最新进展,我们提出了使用变分自编码器建模对手。此外,文献中的许多现有方法假设对手模型在训练和执行期间都可以访问对手的观察和动作。为了消除这个假设,我们提出了一个修改,试图识别潜在的对手模型只使用我们的代理的本地信息,如其观察,行动和奖励。实验表明,我们的对手建模方法实现相等或更大的情景回报,在强化学习任务对另一种建模方法。

英文摘要:

Multi-agent systems exhibit complex behaviors that emanate from the interactions of multiple agents in a shared environment. In this work, we are interested in controlling one agent in a multi-agent system and successfully learn to interact with the other agents that have fixed policies. Modeling the behavior of other agents (opponents) is essential in understanding the interactions of the agents in the system. By taking advantage of recent advances in unsupervised learning, we propose modeling opponents using variational autoencoders. Additionally, many existing methods in the literature assume that the opponent models have access to opponent's observations and actions during both training and execution. To eliminate this assumption, we propose a modification that attempts to identify the underlying opponent model using only local information of our agent, such as its observations, actions, and rewards. The experiments indicate that our opponent modeling methods achieve equal or greater episodic returns in reinforcement learning tasks against another modeling method.
