# v2.1 & v2.0

[Other versions](https://huggingface.co/gustproof/sd-models/tree/main/shinymas)

A LoRA based on 966 Shiny Colors cards, recognizing the 26 characters to varying degrees.

Resumed from [deresute-v1.3-epoch16](https://huggingface.co/gustproof/sd-models/blob/main/deresute/checkpoints/deresute-v1.3-000016.safetensors) by accident instead of training from scratch, 
retaining surprisingly much of the knowledge of Cinderella Girls characters. 
This suggests that it's likely the model's capacity is nowhere close to being reached.

This also serves as a demo of an extremely inefficient style transfer method: train the characters, and then train on lots of unrelated styled images.

## Usage
The style itself doesn't have a trigger word. For the characters, below are the character tags and respective top 20 related tags.

## Training info

Training info
Dataset:
* 996 Shiny Colors cards collected from [シャニマスDB](https://imassc.gamedbs.jp/)

Tags generated with [SmilingWolf/wd-v1-4-convnextv2-tagger-v2](https://huggingface.co/SmilingWolf/wd-v1-4-convnextv2-tagger-v2) with a threshold of 0.35. No balancing and tag cleaning. No distinction between Produce and Support cards.

Inspired by [a 2022 paper](https://openreview.net/pdf?id=Uad23IcIEs), a custom LR scheduler was used:
```
SequentialLR(optimizer, [
    LinearLR(optimizer, 0.1, total_iters=steps_per_epoch),
    CosineAnnealingWarmRestarts(optimizer, steps_per_epoch*2, T_mult=2)
], [steps_per_epoch])
```

Training cost: ~12 T4-hours (in addition to deresute costs)
