Research on the Combined Prediction Model of Residential Building Energy Consumption Based on Random Forest and BP Neural Network by Xuenan Zhang, Jinxin Zhang, Jinhua Zhang, YuChuan Zhang

“…To verify the prediction effect of the RF-BPNN combined model, experiments were performed by using the energy efficiency data set in the UCI database, and the model was evaluated with five indicators: mean absolute error, root mean square deviation, mean absolute percentage error, correlation coefficient, and coincidence index. Compared with the random forest, BP neural network model, and other existing models, respectively, it is proven by the experimental results that the RF-BPNN model possesses higher prediction accuracy and better stability.…”
