Air quality predictions of Ulaanbaatar using machine learning approach

Abstract

Predicting and forecasting air quality is the one of the most essential activity in the Smart City. Recently, there are many study to use the machine learning approaches for evaluating and predicting air quality using big data. The aim of this study is to obtain machine learning model for air quality forecasting using previous air quality station data and the weather data. The air quality depends on multi-dimensional factors including location, time, weather parameters, such as temperature, humidity, wind direction and force, air pressure, etc. There are many machine learning approaches, but artificial neural Network model tries to simulate the structures and networks within human brain. It is convenient for working to find relation between multi parameters. If the neural network could determine the relation of the air quality using the weather and air quality data of last year, it is possible to predict approximately air quality of Ulaanbaatar city. We used features including parameters of temperature, humidity, wind direction, air pressure, PM2.5 and PM10, NO2, CO, SO2 and measuring time to build recurrent neural network model that is the class of artificial neural network. In this work we did machine learning test of neural network algorithm for the air quality prediction using LSTM /long short term memory/ model and discussed machine learning test results. * Speaker PoS(ISGC2021)012Air quality predictions of Ulaanbaatar using machine learning approach Otgonsuvd Badrakh 2
