hose_in-SDXL

Similar dataset to v1, just removed a handful (~15%) of incorrectly tagged images, and low quality images and trained on Noob_vpred.

Training notes:

• Kohya's trainer

• optimizer ADOPT

• optimizer_args

  • "betas=(0.9, 0.9999)" "eps=1e-7"

  • This was the best config for ADOPT I found over the past few weeks training for this size dataset

• DoRa LoCon

• frozen text encoder (increased training time, but I prefer to not touch the TE if possible)

• lr 5e-4

• dim 16

• alpha 8

• conv_dim 8

• conv_alpha 4

• batch 8

• GA 16

• 2.6k images

• flip

• bucket

• resolution 1024

• tag dropout 0.1

• dropout 0.2

• caption_dropout 0.1

• scale_weight_norms 6

• ip_noise_gamma 0.02

• min_snr_gamma 2

• zsnr

• v_pred

• Extras:

  • soft_min_snr instead of the default formula

  • learned timestep loss weights, a small network to learn the loss scale for each timestep. similar goal to min_snr

  • sort important tags to the front and sort separately from others

  • tag implication dropout for all common implied tags ~40% drop
