WebFor example, the performance of CCDC + VCT was superior to that of VCT + CCDC, showing a lower commission rate. The optimal performance was obtained by the ensemble model CCDC + VCT + LT, which had the lowest commission and omission rates among all the ensemble models of 13.85% and 23.53%, respectively ( Table A2 ).
