  • rating:questionable
  • rating:safe

Training Procedure

• 204-272 images per batch (epoch variant)
• 512x512px image size
• Adam optimizer
  • Beta1 = 0.9
  • Beta2 = 0.999
  • Weight decay = 1e-2
  • Epsilon = 1e-08
• Constant learning rate 4e-6
• bf16 mixed precision
• 8 epochs of V1 dataset samples stretched to 512x512px (ignore aspect ratio)
• 9 epochs of V1 dataset samples resized to 512xH or Wx512px with center crop (maintain aspect ratio)
• 2 epochs of V1 dataset samples resized to < 512x512px (maintain aspect ratio)
• 10 epochs of V2 dataset samples resized to < 512x512px (maintain aspect ratio)
• Tags for each sample are shuffled for each epoch, starting from epoch 16
