通过基于文本的自然语言进行通信的协作强化学习代理

Toward Collaborative Reinforcement Learning Agents that Communicate Through Text-Based Natural Language

Stellenbosch University(斯泰伦博斯大学)

Kevin Eloff, Herman A. Engelbrecht

摘要:

协作多代理设置中的代理之间的通信通常是隐式的或直接的数据流。本文认为基于文本的自然语言是一种新的形式的多个代理之间的通信训练强化学习。这可以被认为是迈向真正自主通信的第一步,而无需定义有限的指令集,以及人类和机器人之间的自然协作。灵感来自游戏的盲线索,我们提出了一个环境,其中一个代理使用自然语言的指令,以指导另一个通过迷宫。我们测试了强化学习代理通过离散单词级符号进行有效沟通的能力,并表明代理能够通过有限词汇量的自然语言进行充分沟通。虽然沟通并不总是完美的英语,但代理商仍然能够在迷宫中导航。我们实现了0.85的BLEU分数,这比随机生成的序列提高了0.61,同时保持了100%的迷宫完成率。这是使用我们的参考集的随机基线性能的3.5倍。

英文摘要:

Communication between agents in collaborative multi-agent settings is in general implicit or a direct data stream. This paper considers text-based natural language as a novel form of communication between multiple agents trained with reinforcement learning. This could be considered first steps toward a truly autonomous communication without the need to define a limited set of instructions, and natural collaboration between humans and robots. Inspired by the game of Blind Leads, we propose an environment where one agent uses natural language instructions to guide another through a maze. We test the ability of reinforcement learning agents to effectively communicate through discrete word-level symbols and show that the agents are able to sufficiently communicate through natural language with a limited vocabulary. Although the communication is not always perfect English, the agents are still able to navigate the maze. We achieve a BLEU score of 0.85, which is an improvement of 0.61 over randomly generated sequences while maintaining a 100% maze completion rate. This is a 3.5 times the performance of the random baseline using our reference set.
