摘要

无人机上的自动目标检测对于促进自主操作至关重要。深度学习技术的出现大大提高了目标检测和识别系统的效率。然而,在实际操作环境中实现深度网络进行自主决策提出了几个挑战。一个主要的问题是深度学习算法缺乏透明度,这使得它们的行为对从业者和公众都不可靠。此外,深度网络通常需要大量的计算资源,这对于许多紧凑的便携式平台来说可能是不可行的。本文旨在解决这些挑战,促进深度目标探测器在无人机应用中的集成。我们提出了一个新的解释框架,DetDSHAP,旨在阐明由YOLOv5探测器产生的预测。此外,我们建议利用从我们的解释模型中得出的贡献分数作为YOLOv5网络的创新修剪技术,从而在最小化计算需求的同时实现增强的性能。最后,我们对我们的方法进行了性能评估,展示了其在各种数据集上的效率,包括从无人机安装的摄像头收集的真实数据和已建立的公共基准数据集。

DetDSHAP: Explainable Object Detection for Uncrewed and Autonomous Drones With Shapley Values

DetDSHAP: Explainable Object Detection for Uncrewed and Autonomous Drones With Shapley Values

Automatic object detection onboard drones is essential for facilitating autonomous operations. The advent of deep learning techniques has significantly enhanced the efficacy of object detection and recognition systems. However, the implementation of deep networks in real-world operational settings for autonomous decision-making presents several challenges. A primary concern is the lack of transparency in deep learning algorithms, which renders their behaviour unreliable to both practitioners and the general public. Additionally, deep networks often require substantial computational resources, which may not be feasible for many compact portable platforms. This paper aims to address these challenges and promote the integration of deep object detectors in drone applications. We present a novel interpretative framework, DetDSHAP, designed to elucidate the predictions generated by the YOLOv5 detector. Furthermore, we propose utilising the contribution scores derived from our explanatory model as an innovative pruning technique for the YOLOv5 network, thereby achieving enhanced performance while minimising computational demands. Lastly, we provide performance evaluations of our approach demonstrating its efficiency across various datasets, including real data collected from drone-mounted cameras and established public benchmark datasets.
