# Waraku Chise (Blue Archive)
Came out pretty well I think.  Smaller dataset than Mari, but otherwise very similar settings.

## Usage
Use any or all of these tags to summon Chise:
`chise, halo, red eyes, blue hair`
Hair and eyes are mostly optional if you describe a bit of her outfit as well.
She naturally likes to make her `:o` expression because most art features her doing that.  However I also included images tagged with other expressions.
Use `open mouth`, `closed mouth`, and `parted lips` as necessary to get her to make whatever expressions you want.

For her normal outfit (add as many as necessary):
`braid, japanese clothes, detached sleeves, obi, tabi, geta, sailor collar, blue bow`
Her shoes are weird but they're tagged `geta` and the socks as `tabi`.

For her swimsuit outfit (add as many as necessary):
`side ponytail, swimsuit, striped bikini, see-through, sailor collar, side-tie bikini bottom`
You can also add `pointed ears`, which are usually only visible in her swimsuit outfit.

Weight 1 works fine. Also included epoch 6 in case you find the last epoch to be a bit stubborn with her outfits.

## Training
*All parameters are provided in the accompanying JSON files.*
- Trained on a set of 119 images split by outfit, repeated 10 times (swimsuit) or 14 times (uniform) for 7 epochs (119 images * 10 or 14 repeats / 3 batch size * 7 epochs = 3178 steps)
  - Dataset included a mixture of SFW and NSFW.
- Initially tagged with WD1.4 VITv2 model, then performed heavy pruning and editing.
  - Pruned implicit (`oni horns`) or redundant tags and simplified outfits so that they were always tagged with the same handful of tags
  - Made sure important traits were present and consitently described, and traits like `halo` were consistent with actual visibility
  - Added many facial expression, camera angle, and image composition hints
- Used network_dimension 128 (same as usual) and network_alpha 64 (new)
  - This relies on the new alpha 
- Trained without VAE.
