> Number of bounding box examples vs training examples

Hello,

boxes-train.csv contains bounding boxes for a lot fewer training examples than in file_paths_train.csv. Does this mean that the rest of the images do not have bounding boxes (no biopsy detected lesions)? It seems there are much less bounding boxes provided than the 700 scans for training.

Thanks you!

Hi,
yes, you are correct. Scans without bounding boxes do not contain biopsy-proven lesions. For any detection task, it is important to include 'normals' in the training/testing/evaluation. Hope this helps!
