Evaluation metrics of R2 and RMSE on the test dataset for predicting (a-1, a-2) total generation quantity of HW and (b-1, b-2) generation quantity of MHW. For the same sector, performances of the two models were evaluated on the same test dataset. Industrial sectors involved organic chemical materials manufacture (OCM), chemical pesticides manufacture (CPM), specialized chemical products manufacture (SCP), steel rolling and processing (SRP), metal wire and rope manufacture (MWR), metal surface treatment (MST), electronic circuits manufacture (ECM), biomass energy generation (BEG), and electricity generation using other sources (EGU).
