  1. This table shows different NN configurations that were investigated with the corresponding prediction performance (on both K and Kp indices), evaluated by calculating the RMSE (RMSE values in this table are multiplied by 10) and the CC over the whole validation data set. The three numbers (i.e. 4:5:1) in the first column indicate the number of input, hidden and outputs layers, respectively.
