A hybrid Informer-CNN architecture was used to handle both temporal and non-temporal data for predicting GPR.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The Informer-CNN model demonstrated superior predictive performance over traditional models like Convolutional Neural Networks (CNN), Long Short-Term Memory(LSTM), and Informer. Specifically, in the validation set, the model achieved a mean absolute error (MAE) of 0.0273 and a root mean square error (RMSE) of 0.0360 using the 3%\/3mm criterion. In the test set, the MAE was 0.0327 and the RMSE was 0.0468.
