State estimation of urban air pollution with statistical, physical, and super-learning graph models
This work addresses air pollution monitoring for urban areas, presenting incremental improvements through hybrid and super-learning models.
The paper tackled real-time reconstruction of urban air pollution maps, addressing challenges like heterogeneous data and scarce measurements, and tested methods on Paris, achieving performance results as described in the abstract.
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.
