PM2.5 Concentration Forecasting Based on Data Preprocessing Strategy and LSTM Neural Network

Abstract—In order to better grasp the change rule of PM2.5 concentration, this paper presents a prediction model of PM2.5 concentration based on Complete Ensemble Empirical Mode Decomposition with Adaptive Noise (CEEMDAN)- Permutation Entropy (PE)-Long Short-Term Memory (LSTM). The PM2.5 concentration time series is decomposed into several sub-sequences with obvious complexity differences by CEEMDAN-PE. Then, the LSTM prediction model is built by adding meteorological parameters to each different sub-sequence. The final results are got by adding the prediction results. The data of four monitoring stations in Tangshan City, Hebei Province is used to implement simulation experiment. Experiment results confirm that the proposed prediction model compared with other combined and single forecasting methods, and shows a high prediction precision, and good universality, which provided effective technical support for pre-control of air pollution.

Index Terms—PM2.5, concentration prediction, ensemble empirical mode decomposition, permutation entropy, time series.
