Hi @yuan.qing.bio,
Fantastic - thank you for sharing this!
Regarding Task 3:
- Make sure you don’t have images from the same lesion in your training- and validation splits. That won’t be the case for the test set and you might be disappointed by a much lower accuracy then. With the file posted here you can find out which images correspond to each other in the training images.
- Be aware not “raw” accuracy but balanced accuracy as discussed here is the goal metric for task 3.
