Ntrations around the basis of meteorological and traffic information. Section three describes the components and methods used in this study. Section 4 presents the results of overall performance evaluation. Section 5 summarizes and concludes the study. two. Connected Operate Different Herbimycin A Epigenetics studies happen to be conducted around the harmful effects of air pollution. We classify these research into the following three categories: (1) research that use only meteorological information, (two) studies that use only traffic data, and (3) studies that use meteorological and website traffic information. The subsequent sections go over each and every category in detail.Atmosphere 2021, 12,3 of2.1. Prediction of AQI Working with Meteorological Data Several authors have proposed machine learning-based and deep learning-based techniques for predicting the AQI using meteorological information [16,204]. For example, Park et al. [16] predicted PM2.five concentrations on the basis of meteorological attributes, including temperature, humidity, wind direction, and wind speed. A dataset was collected from two locations in Seoul, South Korea. The study proposed the LSTM and artificial neural network (ANN) models to predict PM concentrations after a particular time. The authors proposed an algorithm that chosen the LSTM or ANN model on an hourly basis. The accuracy from the proposed model was higher than that of your LSTM and ANN models. Lee et al. [20] predicted PM2.five concentrations in Taiwan utilizing the GB model. They utilised a dataset consisting of hourly measurements obtained more than one year from 77 air monitoring stations and 580 meteorological stations in Taiwan. Experimental benefits indicated that the model provided precise 24-h predictions at most air stations. Chang et al. [21] made use of the RF model to predict PM2.5 concentrations on the basis of meteorological attributes such as wind direction, wind speed, temperature, humidity, and rainfall. The authors compared the proposed model with two other time-series data evaluation models: logistic regression and linear discriminant. Experimental results demonstrated that the RF model was one of the most precise for predicting PM2.five concentrations. Choubin et al. [22] assessed the spatial hazard of PM10 concentrations applying three machine studying models: RF, bagged cart, and mixture discriminant evaluation. The study location was chosen from Barcelona, which is an urban and industrial area in Western Europe. The authors assembled a dataset that integrated PM concentrations (PM10 , PM2.five , PM1 , and others) and meteorological characteristics (wind speed, wind path, and so forth.). Moreover, the attributes that affected PM modeling had been identified by a feature choice approach referred to as simulated annealing. Experimental results demonstrated that the accuracies of all 3 machine learning models were greater than 87 for predicting PM10 concentrations. Several studies have employed deep (��)-Darifenacin manufacturer mastering approaches to predict the AQI. For example, Qadeer et al. [23] predicted hourly PM2.five concentrations in two massive South Korean cities (Seoul and Gwangju), together with different pollutants and meteorological capabilities. The pollutant attributes consisted of PM2.5 , PM10 , SO2 , O3 , NO2 , and CO concentrations. The meteorological characteristics consisted of temperature, wind speed, relative humidity, surface roughness, planetary boundary layer, and precipitation. Experimental benefits showed that the LSTM model outperformed the XGBoost, LGBM, recurrent neural network (RNN), and convolutional neural network models in predicting hourly PM2.5 concentrations.
