为无人机自主决策开发支持符号推理的仿真框架,提升复杂任务适应性。

Simulation-based Scenario Generation for Robust Hybrid AI for Autonomy

  • 构建融合符号信息与传感器数据的仿真环境,支持神经符号算法训练
  • 生成含时空约束和概率信息的任务场景,增强推理上下文真实性
  • 适用于需低干预自主的搜救、执法等实际应用,适合算法验证研究者

无人飞行器(UAV)在搜救、应急管理和执法中的应用日益广泛,得益于低成本平台与传感器的发展。混合神经符号人工智能方法的兴起有望进一步推动这些应用向更低人类干预方向发展。然而,现有无人机仿真环境缺乏适配此类混合方法的语义上下文。为此,HAMERITT(用于快速训练与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,支持神经符号算法在自主机动与感知推理方面的训练、测试与验证。该框架具备场景生成能力,可在原始传感器数据之外提供任务相关的符号化上下文信息,包括目标实体及其与场景元素的关系、时间受限的兴趣区域(含先验概率)及区域内限制区域。同时支持在端到端任务运行中分别训练机动与感知算法线程。未来工作将提升场景真实感,并通过自动化流程扩展符号上下文生成能力。

原文摘要 · Abstract (English)

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.
