Dual-channel Feature Fusion Model for Air Pollutants Forecast

Yujie Li, Xu Qiao, Zhiping Liu, Rui Gao

Abstract—Air pollution is severely injurious to human health, and hence short-term prediction for various air pollutants concentrations is beneficial for early prevention and travel planning. To reduce the contradictory information between time trend and variable correlation when predicting, the dual-channel feature fusion model is proposed. The model first obtains the time-series characteristic through the temporal feature extraction module based on TPA-LSTM, then captures the variable relevance with the structural feature extraction module aggregated GNN and LSTM, and finally integrates the two features by a fusion gate to realize forecast. Comparative experiments on air pollutants dataset from the state-controlled air station in Jinan by different models reveal that our method demonstrates superior properties.
