A Hybrid Deep Learning Framework for Network Flow Forecasting of Power Grid Enterprise

Figure 5

The boxplot figures for each benchmark model in terms of inflow and outflow flow series. The 30 values of adjR2 criterion are selected to plot boxplot figures. The 8 boxes for each dataset correspond to the models in sequence: GRU, VMD-GRU, xgboost, VMD-xgboost, VMD-VMD-xgboost, VMD-xgboost with residual adjustment, EMD-xgboost, and the proposed approach. The boxplot figures of xgboost model are omitted because its results have a large gap compared with other models (inflow: 0.6597, outflow: 0.4384).
