“…More neuron nodes can improve the training and generalization ability of the proposed model, but it may also cost more training time and produce an overfitting phenomenon. 47 Therefore, referring to the experience of Shen et al 48 and Yun et al, 49 this paper uses the step-by-step experimental method to determine the optimal network parameters, specifically, we calculate the model training error when the iteration are 50, 100, 200, 300 and the neuron nodes of the proposed model are 4, 8, 16, 32, 64, and 128 separately. The results conclude that when the iteration number is 200 and the neuron node is 128, the error indicators of RMSE, MAE, and RMSE are 0.851783, 0.601614, and 0.021578, respectively (as shown in Table 3), that is the minimum value of the whole test sample.…”
