本文提出HAMERITT仿真框架,通过生成包含符号上下文和时空约束的场景,支持无人机自主机动与感知的神经符号算法训练、测试与保障,弥补现有仿真环境缺乏语义上下文的不足。

摘要:

随着低成本平台和传感器载荷的出现,无人机(UAV)在搜索救援、应急管理和执法中的应用日益受到关注。混合神经与符号人工智能方法在复杂推理中的兴起,有望在减少人工干预的情况下进一步拓展这些应用的边界。然而,当前的无人机仿真环境缺乏适合这种混合方法的语义上下文。为填补这一空白,HAMERITT(用于快速训练和测试的混合人工智能任务环境)提供了一个基于仿真的自主软件框架,支持用于自主机动和感知推理的神经符号算法的训练、测试与保障。HAMERITT具备场景生成能力,除原始传感器数据外,还提供与任务相关的上下文符号信息。场景包括对感兴趣实体及其与场景元素关系的符号描述,以及以带时间约束的感兴趣区域形式呈现的时空约束,这些区域带有先验概率和区域内的受限区域。HAMERITT还支持在端到端任务运行中分别训练机动与感知的不同算法线程。未来工作包括通过自动化工作流提高场景真实感和扩展符号上下文生成。

英文摘要:

Application of Unmanned Aerial Vehicles (UAVs) in search and rescue, emergency management, and law enforcement has gained traction with the advent of low-cost platforms and sensor payloads. The emergence of hybrid neural and symbolic AI approaches for complex reasoning is expected to further push the boundaries of these applications with decreasing levels of human intervention. However, current UAV simulation environments lack semantic context suited to this hybrid approach. To address this gap, HAMERITT (Hybrid Ai Mission Environment for RapId Training and Testing) provides a simulation-based autonomy software framework that supports the training, testing and assurance of neuro-symbolic algorithms for autonomous maneuver and perception reasoning. HAMERITT includes scenario generation capabilities that offer mission-relevant contextual symbolic information in addition to raw sensor data. Scenarios include symbolic descriptions for entities of interest and their relations to scene elements, as well as spatial-temporal constraints in the form of time-bounded areas of interest with prior probabilities and restricted zones within those areas. HAMERITT also features support for training distinct algorithm threads for maneuver vs. perception within an end-to-end mission run. Future work includes improving scenario realism and scaling symbolic context generation through automated workflow.
