具备推断自主代理特征的能力将深刻改变国防、安全与民用应用。此前工作首次证明,监督式神经网络时间序列分类(NN TSC)可在军事背景下快速预测群体自主代理的战术,为反制行动提供情报支持。然而,大多数自主交互(尤其是军事对抗)充满不确定性,质疑了预训练分类器的实际可用性。本文通过利用预期作战变化构建更丰富的数据集,训练出更具鲁棒性的神经网络,在高度不确定场景中表现出更优的推理性能。具体而言,通过模拟防御方数量、运动模式及测量噪声水平的变化,生成多样化数据集。关键发现表明,基于丰富数据训练的鲁棒神经网络具有更高分类准确率,并具备操作灵活性,如降低资源需求、满足轨迹约束。此外,本文提出一种新框架,用于优化训练后神经网络的部署:通过优化防御方轨迹,使其诱发敌方响应,从而最大化神经网络正确分类战术的概率,同时满足对防御方的操作约束。
原文摘要 · Abstract (English)
Having the ability to infer characteristics of autonomous agents would profoundly revolutionize defense, security, and civil applications. Our previous work was the first to demonstrate that supervised neural network time series classification (NN TSC) could rapidly predict the tactics of swarming autonomous agents in military contexts, providing intelligence to inform counter-maneuvers. However, most autonomous interactions, especially military engagements, are fraught with uncertainty, raising questions about the practicality of using a pretrained classifier. This article addresses that challenge by leveraging expected operational variations to construct a richer dataset, resulting in a more robust NN with improved inference performance in scenarios characterized by significant uncertainties. Specifically, diverse datasets are created by simulating variations in defender numbers, defender motions, and measurement noise levels. Key findings indicate that robust NNs trained on an enriched dataset exhibit enhanced classification accuracy and offer operational flexibility, such as reducing resources required and offering adherence to trajectory constraints. Furthermore, we present a new framework for optimally deploying a trained NN by the defenders. The framework involves optimizing defender trajectories that elicit adversary responses that maximize the probability of correct NN tactic classification while also satisfying operational constraints imposed on the defenders.
