摘要:
本文提出了一种多智能体强化学习(MARL)框架,利用领域知识驱动的奖励实现无人机集群的协同避碰。该奖励源自图像处理领域的知识,通过在二维场上近似等高线来构建。通过将障碍物建模为场上的极大值,由于等高线不会穿过峰值或相交,因此能固有地避免碰撞。此外,等高线平滑且节能。由于最小化了智能体交互,并消除了最先进MARL方法中对复杂信用分配方案或观测共享机制的需求,该框架能够支持大规模集群的训练。此外,通过强化训练,无人机获得了适应等高线可能不可行或不存在的复杂环境的能力。进行了大量实验以评估本框架相对于最先进MARL算法的性能。
英文摘要:
This paper presents a multi-agent reinforcement learning (MARL) framework for cooperative collision avoidance of UAV swarms leveraging domain knowledge-driven reward. The reward is derived from knowledge in the domain of image processing, approximating contours on a two-dimensional field. By modeling obstacles as maxima on the field, collisions are inherently avoided as contours never go through peaks or intersect. Additionally, counters are smooth and energy-efficient. Our framework enables training with large swarm sizes as the agent interaction is minimized and the need for complex credit assignment schemes or observation sharing mechanisms in state-of-the-art MARL approaches are eliminated. Moreover, UAVs obtain the ability to adapt to complex environments where contours may be non-viable or non-existent through intensive training. Extensive experiments are conducted to evaluate the performances of our framework against state-of-the-art MARL algorithms.
