# BUS-COT Training Bundle
This public dataset repository packages the training inputs and checkpoints used
for the BUS-COT breast-ultrasound experiments.
## Contents
- `data/training_csvs/`: GMPO and positive-only CLIP training CSV files.
- `data/image_assets/`: positive images, GMPO negative images, and lesion masks.
- `data/vqa/full_train_and_test_data/`: BUS-COT VQA train/test JSON files.
- `checkpoints/upstream/`: selected GMPO `oa25_like_012` epoch-3 checkpoint.
- `manifests/`: GMPO-selection and evaluation summaries.
## Selected GMPO
The only uploaded checkpoint is GMPO `oa25_like_012`, epoch 3, with global
four-way weights `[0.5, 0.5, 1.0, 0.25]`.
## Important Notes
- The UDIAT segmentation result was used to choose among GMPO candidates; it is
not an independent blind-final-test estimate.
- Users are responsible for verifying the source data licence, consent status,
institutional approval, and suitability for their intended use.
