Abstract

In order to improve the long-term prediction accuracy of PM2.5, this paper proposed a TSMN(time series memory network) prediction model based on deep learning by taking air pollutants and meteorological factors as the influencing factors. The model consisted of two components. The local memory component used external memory to improve the long-range memory capacity of the model, and cooperated with the neighborhood component that modeled the multi-site spatial relationship to complete long-term prediction of PM2.5 from the perspective of time and space. This paper compared the TSMN model with multiple models by using different evaluation indicators. Comparing the TSMN model with the better-performing CNN-LSTM model, the RMSE and MAE of this model goes down 5.2% and 5.7% respectively, and the R2 goes up 7.5%. The experimental results show that the TSMN model can effectively improve the long-term prediction accuracy of PM2.5 concentration.
