Training info

Training info Dataset:

• 1065 Battle Girl High School cards collected from bg-search (exact duplicates merged)

Tags generated with SmilingWolf/wd-v1-4-convnextv2-tagger-v2 with a threshold of 0.35. No balancing and tag cleaning.

Inspired by a 2022 paper, 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: ~4 T4-hours
