## Usage
Use any or all of these tags to summon Chise: `chise, halo, oni horns, hair flower, red eyes, blue hair`
For her normal outfit: `braid, japanese clothes, detached sleeves, bridal gauntlets, obi, tabi, geta, sailor collar, blue bow`
For her swimsuit alt: `side ponytail, swimsuit, striped bikini, see-through, see-through shirt, white sailor collar, side-tie bikini bottom`
- You may also add `pointy ears`, which are usually only visible in her swimsuit outfit.
## Training
*Exact parameters are provided in the accompanying JSON files.*
- Trained on a set of 119 images; 76 swimsuit, 43 normal.
- 15 repeats for normal outfit
- 9 repeats for swimsuit outfit
- 3 batch size, 4 epochs
- `(76*9 + 43*15) / 3 * 4` = 1772 steps
- 0.0837 loss
- 832x832 training resolution
- `constant_with_warmup` scheduler
- Initially tagged with WD1.4 Convnext-v2 model, then heavily edited.
- Pruned redundant tags and simplified outfit tags such that Chise's outfit was always described with the same words
- Ensured unique traits such as `halo` were consistent with actual visibility
- Added many tags for facial expressions, camera angles, and image composition
- Used network_dimension 128 (same as usual) / network alpha 128 (default)
- Resized to 32dim after training
- Trained without VAE.

## Revisions
- v5b (2023-02-12)
- Completely re-trained to correct issue where caption files were not being loaded correctly. New version should have more flexibility but requires additional outfit prompting.
- v1 (2023-01-26)
- Initial release.
- **Issue:** caption files were completely ignored during training. As a result, prompting "chise" grants a very strong effect, but the LoRA is highly overfit.
## Alternate Version - v1
**v1** is also available. This version was improperly configured and ignored caption files, so it was trained on the word `chise` only. It looks quite good, however the model is very overfit and it is difficult to adjust Chise's outfit.
