摘要

层次化组织是生物系统和人类社会的基石,然而人工智能系统往往依赖单一架构,这限制了其适应性和可扩展性。当前的层次化强化学习(HRL)方法通常将层次限制为两级或需要集中式训练,从而限制了其实际应用。我们提出了TAME智能体框架(TAG),这是一个构建完全去中心化层次化多智能体系统的框架。TAG通过新颖的LevelEnv概念,将每一层次抽象为上层智能体的环境,从而支持任意深度的层次结构。这种方法在保持松散耦合的同时,标准化了层级间的信息流动,使得不同类型智能体能够无缝集成。我们通过实现跨多个层次结合不同RL智能体的层次化架构,证明了TAG的有效性,并在标准基准测试中超越了传统多智能体RL基线。我们的结果表明,去中心化的层次化组织不仅提升了学习速度,还提高了最终性能,使TAG成为可扩展多智能体系统的一个有前景的方向。

Hierarchical organization is fundamental to biological systems and human societies, yet artificial intelligence systems often rely on monolithic architectures that limit adaptability and scalability. Current hierarchical reinforcement learning (HRL) approaches typically restrict hierarchies to two levels or require centralized training, which limits their practical applicability. We introduce TAME Agent Framework (TAG), a framework for constructing fully decentralized hierarchical multi-agent systems.TAG enables hierarchies of arbitrary depth through a novel LevelEnv concept, which abstracts each hierarchy level as the environment for the agents above it. This approach standardizes information flow between levels while preserving loose coupling, allowing for seamless integration of diverse agent types. We demonstrate the effectiveness of TAG by implementing hierarchical architectures that combine different RL agents across multiple levels, achieving improved performance over classical multi-agent RL baselines on standard benchmarks. Our results show that decentralized hierarchical organization enhances both learning speed and final performance, positioning TAG as a promising direction for scalable multi-agent systems.
