question about data division

[Xiong-Huiyu]

hello. this work is very enlightening. but for the experimental part, I have some problems. from the appendix, i find there are 4 classes left in cifar100. they are not belong to any classes you dividied. i feel confused. why you don't use them? and what's the difference between unknown classes and open-world classes?
