A Parallel Multi-Demonstrations Generative Adversarial Imitation Learning Approach on UAV Target Tracking Decision

Aiming at the problems of autonomous decision-making and local convergence that occur in traditional reinforcement learning in the Unmanned Aerial Vehicle (UAV) target tracking, this paper proposes a parallel multi-demonstrations generative adversarial imitation reinforcement learning algorithm (PMG) to achieve control of UAVs, and allow them quickly track the target. First, we classify different expert demonstrations according to different tasks to maximize the model to learn all expert experience. In addition, we develop a parallel multi-demonstrations training framework based on generative adversarial imitation learning (GAIL), and design strategy update methods for different types of generators, which ensures the generalization ability of imitation learning while improving training efficiency. Finally, we integrate deep reinforcement learning with imitation learning. During the initial training phase, our focus lies on imitation learning while periodically transferring expert knowledge to the pool of reinforcement learning experiences. In the later stages, we increase the proportion of reinforcement learning training and achieve effective UAV target tracking through fine-tuning the weights obtained from reinforcement learning. Experimental results demonstrate that compared to existing reinforcement learning algorithms, our algorithm effectively mitigates issues such as local convergence and completes training in a shorter timeframe, ensuring stable target tracking by UAVs.
