SimSiam (ResNet-18 backbone, trained from scratch on CIFAR-10 with solo-learn)
Dimensional collapse
SimSiam (ResNet-50 backbone)
no structures recorded for this checkpoint specifically

Observations (1)

In BYOL, SimSiam, SwAV and DINO on CIFAR-10 the target branch has higher effective rank than the online branch, which the authors prove follows from a low-pass online spectral filter and argue alleviates dimensional collapse
