Hello Everyone I hope your all having more fun than you can handle today!
I have been following A walk with fastai2 - Study Group and Online Lectures Megathread being run buy muellerzr and we covered a little bit about dealing with classes that your classifier hasn’t been trained on.
If you look at this notebook you will see a way of using multilabel classification to recognize images that your classifier has not been trained on.
It looked good to me.
