Dataset related to the article "UPVnet: A Neural Network for Accurate First-Arrival Picking in Ultrasonic Pulse Velocity Testing of Rock Samples"

The compressed folder contains ultrasonic pulse velocity testing data for 172 P- and S-waves of 7 types of rocks mentioned in the article, as well as demonstration code for UPVnet. Note: Data augmentation generated 4500 training and 500 validation waveform datasets, stored in the .npz files in the "data" folder. In "UPVnet.ipynb", if "data_augmentation=True", data augmentation is reapplied; otherwise, the ".npz" files in the data folder are directly accessed. In UPVnet.ipynb, when "train_mode=True", the model is retrained. Otherwise, the model parameters are directly loaded from the ".pt" file in the "data" folder. All ultrasonic waveform data are saved in the "datasets" folder, named according to the format "(sample number)_(transducer type)_(measurement distance)_(experiment number)". "Calibration" indicates the calibration of the transducers.
