Separate section for unsupervised continual learning

[DonkeyShot21]

Hey, I'll just leave it here as an idea, it would be nice to have a section for "Unsupervised Continual Learning" or something like that. It is a hot topic nowadays, and there are enough papers to have a separate section. Some examples: https://arxiv.org/abs/2112.04215 https://arxiv.org/abs/1910.14481 https://arxiv.org/abs/2110.06976

That's a great idea! I'm doing a cleanup of the repo soon. Will create the section and add those. Thks
