Evaluation of the networks during training as a function of the number of neurons in the hidden layer(s) N_h. The evaluation was made using the set of 29 evaluation signals, not used for training, for all of the configurations of the networks considered in this paper. The loss is calculated as an average evaluation loss of all evaluation signals. For the loss values on the vertical axes in the graphs, the best evaluation loss found after the given number of epochs was used.
