 ### Data preparation
 
-To directly run the train and validation script in this directory, data preparation needs to be done. The [OneDrive link](https://hkustgz-my.sharepoint.com/:f:/g/personal/bcao686_connect_hkust-gz_edu_cn/EhdJLtou8I1MoUJCu-KCoboBfi-wOp00WAlQCrONxjoYgg?e=rltgFE) contains all the training and synthetic testing data used in this work, stored in data.zip. This link also contains the pretrained model for single-phase and di-phase identification.
