In order to characterize the accuracy, the mean absolute error (MAE), median absolute error (MdAE), root mean square error (RMSE) were computed, 10-fold cross-validation is used, unless otherwise specified. For the comparison purpose, the "black box" models created using previously published software are considered. A detailed description of this software and machine learning models is given in our previous work . To evaluate the accuracy of the models, we also used 10fold cross-validation (the "CV" command line option of the above-mentioned software).
