Abstract

This paper repeated experiments for many times, and simplified the original five water quality categories into two categories, based on the samples of water quality monitoring in Beijing Tianjin Hebei Haihe River Basin. Based on water quality classification, the three most obvious variables of stratification: turbidity, total phosphorus and total nitrogen are selected. The k-nearest neighbor method is used to predict the classification results of the test set, and the accuracy is about 75%.
