Study on Urban Wastewater Discharge Forecasting and Influence Factors Analysis Based on Stochastic Gradient Regression

The prediction of urban wastewater discharge and influence factors analysis plays an important role in protection and development of urban water resources. In this paper, a prediction model of urban wastewater discharge was set up based on stochastic gradient boosting, and applied to wastewater discharge of Tianjin. In comparison with support vector machine method and multivariate adaptive regression splines method, the method of stochastic gradient regression has higher precision. The study will provide a creditable theoretical support for wastewater discharge management.
