Gmean and AUC scores for the BRF, EEC, XGB, and CAT algorithms across all the 11 datasets (feature types). The average Gmean and AUC of each algorithm across all the datasets is shown in the last row; and the average Gmean and AUC of each feature type across all four algorithms is shown in the last two columns
