摘要:

在预测PM2.5浓度时,需要考虑复杂的信息来源,因为浓度在很长一段时间内受到各种因素的影响。在本文中,我们确定了一组关键领域的知识PM2.5预测和开发一种新的基于图形的模型,PM2.5-GNN,能够捕捉长期的依赖关系。在一个真实的数据集上,我们验证了所提出的模型的有效性,并考察了其捕获细粒度和长期影响PM2.5过程的能力。拟议的PM2.5-GNN亦已在网上部署,以提供免费预报服务。

英文摘要:

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 dependencies. On a real-world dataset, we validate the effectiveness of the proposed model and examine its abilities of capturing both fine-grained and long-term influences in PM2.5 process. The proposed PM2.5-GNN has also been deployed online to provide free forecasting service.
