This dataset was a YOLOv8 model, with v6 being YOLOv8m.
In the future, you can see the model type yourself, which is listed under each Universe model page. If you click on the “View Version” link next to the listing for the dataset it was trained on, you will be able to find the dataset version which will have the preprocessing and augmentation steps.
Other than information publically available through those pages, we either do not have or cannot share any other information.
Hope this helps
