## Usage
Use any or all of the following tags to summon momoka: `momoka, halo, short twintails, horns, bright pupils, pointy ears, hair ornament, ahoge`
- Add `(dragon tail:1.3)` for her tail (even though I'm not quite sure Momoka is truly a dragon?)
For her normal outfit: `sleeveless dress, collared dress, blue necktie, white open jacket, off shoulder, loose socks, white shoes`
- Add `frilled dress` if the frills at the bottom of her dress are not correctly displayed.
For her accessories: `potato chips, bag of chips, holding food`
For her smug expression: `smug, open mouth, sharp teeth, :3, :d`
- Alternatively, `smug, grin, sharp teeth, smile` for a toothy grin
[Here is a list of all tags including in the training dataset, sorted by frequency.](all_tags.txt)
## Training
*Exact parameters are provided in the accompanying JSON files.*
- Trained on a set of 94 images.
- 13 repeats
- 3 batch size, 4 epochs
- `(94 * 13) / 3 * 4` = 1654 steps
- 0.0737 loss
- Initially tagged with WD1.4 swin-v2 model. Tags pruned/edited for consistency.
- `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 24 after training
- This LoRA seemed very slightly overtrained, perhaps due to smaller dataset, so resizing to 24 appeared a bit better than 32.
- Training resolution 832x832.
- This one also came out better at 832 vs 768.
- It's not clear to me why some LoRAs perform substantially better at 768 and others at 832.
- Trained without VAE.
