PM2.5-GNN [PDF]

open access: yesProceedings of the 28th International Conference on Advances in Geographic Information Systems, 2020
When predicting PM2.5 concentrations, it is necessary to consider complex information sources since the concentrations are influenced by various factors within a long period. In this paper, we identify a set of critical domain knowledge for PM2.5 forecasting and develop a novel graph based model, PM2.5-GNN, being capable of capturing long-term ...
