## Training
*Exact parameters are provided in the accompanying JSON files.*
- Trained on a set of 280 images.
  - 7 repeats
  - 3 batch size, 4 epochs
  - `(280 * 7) / 3 * 4` = 2614 steps
  - Kazusa has a lot of good art so her dataset is much larger than usual.  This seems to have let me train for longer without overfitting.
- 0.08 loss
- Initially tagged with WD1.4 swin-v2 model. Tags pruned/edited for consistency.
  - [Detailed tagging methodology here.](tagging%20methodology.md)
- `constant_with_warmup` scheduler
- 1.5e-5 text encoder LR
- 1.5e-4 unet LR
- 1e-5 optimizer LR
- Used network_dimension 128 (same as usual) / network alpha 128 (default)
  - Resized to 16 after training
- Training resolution 832x832.
- Trained without VAE.
