Training info

Trained solely on 164 640x800 frameless Cinderella Girls Cards and 273 1280x824 Starlight Stage Cards collected from アイマスシンデレラガールズカードギャラリー without balancing and tag cleaning. Near-duplicates were found (minor differences like closed/open eyes), but they were not cleaned. As the jpgs are highly compressed, they are passed through RealESRGAN_x4plus_anime_6B with --outscale=1 in order to remove the artifacts. Tags generated with SmilingWolf/wd-v1-4-swinv2-tagger-v2 with a threshold of 0.35. Caption template was "[char_name], [filewords]".

Originally trained with LoRA on convolution blocks ("LoCon"), but it was found that removing the convolution weights from the output doesn't alter the results significantly. The original is available as v1-full

and the conv-pruned version is v1-linear

Training cost: ~4.5 T4-hours
