| Abstract: | The prediction of city municipal and domestic water consumption plays an important role in utilization of urban water resources. A prediction model of city municipal and domestic water consumption was set up based on stochastic gradient boosting, and applied to water consumption of Tianjin. In comparion with support vector machine, the method of stochastic gradient boosting has higher precision. The study will provide a creditable theoretical support for water consumption programming. |
| Keywords: | stochastic gradient regression city municipal and domestic water consumption prediction gradient boosting |
