Fig. 7: Experimental feedback to ANN model.

a Comparison of the capacitances and BET surface areas reported in this work with previously reported values. For literature data, only those with high capacitances above 100 F/g were selected and plotted. b Correlated capacitance vs experimental capacitance for the ANN model with the additional experimental data. Train RMSE = 33.0, Val RMSE = 35.6, Test RMSE = 46.2. c Capacitance vs the surface areas of micropores and mesopores when doped with 2.3% nitrogen and 20% oxygen at 5 mV/s. d Specific capacitance vs O/N content for carbon materials with S_micro = 1710 m²/g, S_meso = 1050 m²/g at 5 mV/s.
