## Usage
_※ Hibiki's outfits are rather complicated, so I have documented all of her tags here for your reference. It may not be necessary to use all of them._
Use any or all of these tags to summon Hibiki: `hibiki, halo, dog ears, bright pupils, goggles on head, black hair, dog tail`
For her normal outfit: `twintails, hair bobbles, engineering goggles, purple choker, multicolored jacket, black camisole, grey shirt, black shorts, fishnet pantyhose, dog tags`
For her cheerleader alt: `cheerleader, ponytail, crop top, wing collar, criss-cross halter, pleated miniskirt, pom pom (cheerleading)`
- Use `cheerleader` to strengthen or weaken the effect.
- If the stickers appear on incorrect outfits, add `star sticker, sticker on face, sticker on arm` to the negative prompt.
- If her name tag and collar appear on incorrect outfits, add `wing collar` to the negative prompt.
Calm expression: `light smile, expressionless`
Embarrassed expression: `blush, embarrassed, wavy mouth, open mouth`
Weapon: `mortar (weapon), rocket, mortar shell, suitcase, m logo`
Weight 0.9 - 1.0 should be ideal. The LoRA is slightly overfit, I'll probably retrain it with slightly fewer steps in the future. It's still a substantial improvement over the previous version and is reasonably flexible with Hibiki's outfit.
## Training
*Exact parameters are provided in the accompanying JSON files.*
- Trained on a set of 162 images; 82 cheerleader, 80 normal.
- 8 repeats for normal outfit
- 7 repeats for cheerleader outfit
- 3 batch size, 4 epochs
- `(82*7 + 80*8) / 3 * 4` = 1619 steps
- 0.0905 loss
- 832x832 training resolution
- `constant_with_warmup` scheduler
- Initially tagged with WD1.4 swin-v2 model, then heavily edited
- Used network_dimension 128 (same as usual) / network alpha 128 (default)
- Resized to 32dim after training
- Trained without VAE.

## Revisions
- v3 (2023-02-13)
- Retrained from scratch since the original LoRA was not very good.
- Added many new images to the dataset, particularly for Hibiki's regular outfit.
- Completely re-tagged the dataset. Used WD1.4 swin-v2 as a starting point, then performed extensive editing and cleanup for accuracy and consistency. Added many new tags to better describe Hibiki's outfits and expressions.
- Uses improved hyperparamters from my more recent models.
- v1 (2023-01-10)
- Initial release.
