In this study, Air Quality Index (AQI) in Besiktas was intended to be predicted by Artificial Neural Networks (ANN) and k Nearest Neighbors (kNN) algorithms. For purpose, eight parameters have been selected which may affect the AQI. These are PM10, SO2, CO, O3, temperature, humidity, pressure wind speed, respectively. 124 data for 2015, 2016, 2017 2018 January, includes parameters, were determi...
