Harmful air pollutant such as PM2.5 is still a major concern in many countries. At high concentrations, it could lead to adverse health effect on human, escalating the risk of cardiovascular and respiratory diseases. In order to mitigate this issue, continuous air quality monitoring systems have been deployed to alert the general public of high PM2.5 level. However, such monitoring system requires substantial budget and resources to construct, thus may not be accessible in some regions especially developing countries. Therefore, it is important to develop a high performance PM2.5 prediction model that only employs easily attainable input parameters as a more cost-effective alternative. In this study, common meteorological data from five different cities in China were utilized for the PM2.5 prediction model. Dynamic model such as the nonlinear autoregressive network with exogenous inputs (NARX) with different input/output time lag were applied to transform training dataset into different data structures. Additionally, machine learning algorithms were analysed and evaluated to predict PM2.5, namely: multi-linear regression (MLR), and feed-forward artificial neural network (FANN). The results shows that FANN model with 10 hidden neurons using NARX-2 data structure is the best model combination with an R2 values of up to 0.973.
