To upload data using the uploader, go to the Data acquisition page and click on the uploader button as shown in the image below:
When uploading your data, you can choose the category you want your data to fall in i.e training set, testing set or automatically split the dataset between training and testing set. You can also choose whether to infer labels from files name or enter a label of which the files should automatically fall in.
