## What's what

`1_json_to_csv.py`:  
 - converts cm_tags.json to a csv format I'm more used to and that is easier to use with my existing tooling

`2_retrieve_images_by_cc.py`:  
 - retrieves the validation images using cheesechaser, downloads them to "original/"

`3_common_tags.py`:  
 - clean up both models tag sets to only consider the common tags; note down the indexes to use to fetch the correct tag probs from the dumps generated by the inference scripts

`4_cm_onnx_inference.py`:  
 - run inference using the ONNX model of camie-tagger, dump the activated (post-sigmoid) outputs

`5_wd_v3_onnx_inference.py`:  
 - run inference using the ONNX model of wd_v3 taggers (hardcoded to use swinv2_v3, could be made to use any of the v3 series), dump the activated outputs

`6_get_labels.py`:  
 - get one-hot encoded labels from val_dataset.csv, dumps them to "labels.npy"

`7_analyze_metrics_macro.py`:  
 - final analysis tool

## Caveats

The swinv2_v3 tagger has got an unfair home advantage, in that out of the 20116 validation samples, only 2908 are guaranteed to not have been part of the training set.

Gathering a more fair validation set is left as an exercise for the reader.  
The exact datasets splits use for wd_v3 models are available here: https://huggingface.co/datasets/SmilingWolf/wdtagger-v3-seed

The analysis script removes tags that have no positive samples in the val set.  
It would probably be a good idea to only select tags that have 5+ samples.  
It's a fairly trivial change to make to the analysis script, if one feels so inclined.

I have only used the tags that have the exact same name and category to build the common tag set. I haven't adjusted for aliases and implications.
