摘要:
In recent years, the Chinas economy has developed rapidly. The peoples living standard has been improved. The number of cars has been increasing, and the pollutant NO has been produced continuously, which leads to the formation of NO2. These harmful particles have an impact on human health. Thus, the effective and accurate NO2 concentration prediction model plays an effective role in peoples health and prevention. For this problem, this paper presents a prediction model based on the long short-term memory (LSTM) method to predict NO2 concentration. Firstly, the PM10, SO2, NO2, CO, O3, temperature in a campus monitoring point in Beijing is collected as the research object in this paper. Then, the LSTM prediction model and BP (back propagation) neural network prediction model are established respectively. Finally, the accuracy of the two prediction models for the prediction of NO2 concentration is compared. The results show that the prediction model based on LSTM method is superior to BP neural network model, and the prediction accuracy is more accurate. © 2021, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
