WD ConvNext Tagger v3

Supports ratings, characters and general tags.

Trained using https://github.com/SmilingWolf/JAX-CV.
TPUs used for training kindly provided by the TRC program.

Dataset

Last image id: 7220105
Trained on Danbooru images with IDs modulo 0000-0899.
Validated on images with IDs modulo 0950-0999.
Images with less than 10 general tags were filtered out.
Tags with less than 600 images were filtered out.

Validation results

v2.0: P=R: threshold = 0.2682, F1 = 0.4419
v1.0: P=R: threshold = 0.2570, F1 = 0.4282

What's new

Model v2.0/Dataset v3:
Trained for a few more epochs.
Used tag frequency-based loss scaling to combat class imbalance.

Model v1.1/Dataset v3:
Amended the JAX model config file: add image size.
No change to the trained weights.

Model v1.0/Dataset v3:
More training images, more and up-to-date tags (up to 2024-02-28).
Now timm compatible! Load it up and give it a spin using the canonical one-liner!
ONNX model is compatible with code developed for the v2 series of models.
The batch dimension of the ONNX model is not fixed to 1 anymore. Now you can go crazy with batch inference.
Switched to Macro-F1 to measure model performance since it gives me a better gauge of overall training progress.

Runtime deps

ONNX model requires onnxruntime >= 1.17.0
