*3.4. Comparison with Other Models*

We aimed to compare the prediction results of the ANN-WT-LSTM model with other existing models, compare the prediction accuracy of the different models, and analyze the prediction efficiency of the models. The comparison results of the model predictions are shown in Table 6.
