Description

technical field

[0001] The invention belongs to the technical field of air pollutant concentration prediction, and in particular relates to an air pollutant concentration prediction method integrating machine learning and LSTM. Background technique

[0002] In recent years, air pollution has gradually become a very serious problem. The continuous deterioration of air quality has caused great harm to people's health and living environment, and people have begun to pay attention to it in their daily lives. Therefore, the prediction of the concentration of air pollutants is very important, but the analysis and prediction of air pollutants are complex, dynamic and random. To make accurate predictions, a large amount of data from multiple fields and departments is involved. Such as meteorological data, industrial data, environmental data, etc. At present, there are a large amount of monitoring data on air pollution sources, pollutants and meteorology in the society. Making full ...
