Experimental Outputs & Images

To keep the repository lightweight, large artifacts are not stored in git. They live on the HuggingFace Hub and are reproducible from the code here. The full layout is in hf.md.

Artifact Size Where How to regenerate
Main image set (data/images/{gpt,imagen4ultra}_image_gen/) ~2.7 GB HF dataset MLL-Lab/MultiBBQ (embedded in parquet) notebooks/gen_images_*.ipynb
Real-world images (data/images/real_world_image/) ~130 MB HF dataset MLL-Lab/MultiBBQ-realworld notebooks/gen_realworld.ipynb
Perturbed image sets (data/images/gpt_image_gen_<type>/) ~16 GB HF dataset MLL-Lab/MultiBBQ-perturbations perturbation transforms of the main set
Raw inference outputs (results/) ~330 MB HF dataset MLL-Lab/MultiBBQ-results multibbq run ... (see main README)
Computed metrics (analysis/) ~110 MB HF dataset MLL-Lab/MultiBBQ-results multibbq pipeline --input results/ --output analysis/

Getting the images

pip install -e ".[hf]"
multibbq download          # main set -> ./data/images/; --realworld / --perturbations / --all

The complete download guide (all methods, sizes, landing paths) is installation.md Dataset & images section.

Reproducing the analysis from raw outputs

Fetch the released outputs (or any slice of them), then run the pipeline:

hf download MLL-Lab/MultiBBQ-results --repo-type dataset --include "results/gpt_image_gen_main/**" --local-dir .
pip install -e .
multibbq pipeline --input results/gpt_image_gen_main --output analysis/gpt_image_gen_main

The released results/ cover the experiments reported in the paper; the toolkit's extension settings (img_label, context_unmasked, llm) and the perturbation baselines (brightness, contrast) have no released outputs.

Only the dataset metadata (data/metadata/), the construction materials (data/construction/), and the small preview (data/images_sample/) are tracked in git.
