Table 1.

Performance of the ANNs as a function of the learning rate.

Training Set Test Set
LR Score r² MAE RMSE RAE RRSE q² MAE RMSE RAE RRSE
0.1 0.80 0.79 0.65 0.82 65 68 0.85 0.6 0.75 59 61
0.2 0.76 0.80 0.58 0.76 59 64 0.78 0.66 0.84 65 68
0.3 0.77 0.79 0.60 0.77 60 65 0.78 0.67 0.89 66 72
0.4 0.75 0.80 0.58 0.77 59 64 0.77 0.69 0.94 68 76

Note: LR = learning rate; r2 = correlation coefficient for the training set; q2 = correlation coefficient for the test set (r2pred); RMSE = root mean square error; MAE = mean absolute error; RAE = relative absolute error; RRSE = root relative squared error; score = (1 − |(r2q2)|) × q2.
