城市空气污染的状态估计:基于统计、物理与超学习图模型

State estimation of urban air pollution with statistical, physical, and super-learning graph models

Matthieu Dolbeault, Olga Mula, Agustín Somacal

AI总结:

针对城市空气污染实时重建的挑战,提出基于城市图的统计、物理及混合方法,并结合超学习模型,在巴黎内城验证了性能。

摘要:

我们考虑城市空气污染地图的实时重建问题。由于可用数据的异质性来源、直接测量的稀缺性、噪声的存在以及需要考虑的大面积区域,该任务具有挑战性。在本工作中,我们引入了基于将问题置于城市图上的不同重建方法。我们的策略可分为完全数据驱动、物理驱动或混合型,并将其与超学习模型相结合。这些方法的性能在法国巴黎内城案例中进行了测试。

英文摘要:

We consider the problem of real-time reconstruction of urban air pollution maps. The task is challenging due to the heterogeneous sources of available data, the scarcity of direct measurements, the presence of noise, and the large surfaces that need to be considered. In this work, we introduce different reconstruction methods based on posing the problem on city graphs. Our strategies can be classified as fully data-driven, physics-driven, or hybrid, and we combine them with super-learning models. The performance of the methods is tested in the case of the inner city of Paris, France.
