vit-beatrix-geometry-pretrained

This version essentially imploded when learning cutmix cifar100, and yet the geometry held the entire time through a cutmix gauntlet that could not be overcome.

I plan to run a few experiments on it with the geometric and simplex blocks frozen. As it stands, the geometric side is essentially a scaffold of cutmix potential, however this scaffold is limited. It must be further trained, but this is a good basline test.

I will run 4 full trains to test the potential;

1. Frozen geometry, no augmentation. It's working, but overfitted by epoch 30 - which, took nearly 60 before. So that's interesting and yet overfitted.
2. Full augmentation no cutmix/mixup using cifar10 augs.
3. Unfrozen cross-attention only, full augs.
4. Unfrozen cross-attention only, no augs.
