摘要:

我们进行了一项实证研究,发现有序的集体动力学获得的人口的情报代理,由百万代理强化学习。我们的目的是将智能代理放入模拟的自然环境中,并验证在现实世界中开发的原则是否也可以用于理解人工创建的智能群体。为了实现这一点,我们模拟了一个大规模的捕食者-猎物世界,其中世界的法则仅由自然界中发现的发现或逻辑等价物设计。基于深度强化学习(Deep Reinforcement Learning,DRL),赋予智能体智能。为了将种群规模扩展到数百万个智能体,提出了一种具有重新设计的经验缓冲区的大规模DRL训练平台。我们的研究结果表明,人口动态的人工智能智能体,只驱动每个代理的个人的自我利益,揭示了一个有序的模式,这是类似的Lotka-Volterra模型研究人口生物学。在研究智能体群体行为如何随环境资源变化的过程中,我们进一步发现了群体适应的涌现行为。这两个发现都可以用自然界中的自组织理论来解释。

英文摘要:

We conduct an empirical study on discovering the ordered collective dynamics obtained by a population of intelligence agents, driven by million-agent reinforcement learning. Our intention is to put intelligent agents into a simulated natural context and verify if the principles developed in the real world could also be used in understanding an artificially-created intelligent population. To achieve this, we simulate a large-scale predator-prey world, where the laws of the world are designed by only the findings or logical equivalence that have been discovered in nature. We endow the agents with the intelligence based on deep reinforcement learning (DRL). In order to scale the population size up to millions agents, a large-scale DRL training platform with redesigned experience buffer is proposed. Our results show that the population dynamics of AI agents, driven only by each agent's individual self-interest, reveals an ordered pattern that is similar to the Lotka-Volterra model studied in population biology. We further discover the emergent behaviors of collective adaptations in studying how the agents' grouping behaviors will change with the environmental resources. Both of the two findings could be explained by the self-organization theory in nature.
