Dataset Viewer
The dataset could not be loaded because the splits use different data file formats, which is not supported. Read more about the splits configuration. Click for more details.
Couldn't infer the same data file format for all splits. Got {NamedSplit('train'): ('imagefolder', {}), NamedSplit('test'): ('json', {})}
Error code:   FileFormatMismatchBetweenSplitsError

Brain MRI Upstream Experiment Data

This export contains the exact leakage-free Brain MRI upstream vision encoder training pairs and Figshare segmentation evaluation inputs.

Training

train/csv/brain_mri_dpo_sd_neg100_mmneuro_benchmark_excluded_12644.csv has 12,644 rows. filename, filename_neg, and mask_path are relative to this export root. Caption is the tumor-presence caption and Caption_neg is the same base caption followed by a neg100 tumor-absence sentence.

Segmentation Test

test_figshare3064/ has the Figshare image/mask pairs. generic_prompts.json is the single generic-prompt condition. metadata_oracle_random10_tumortype_seed0.* is the separate oracle condition that inserts the public Figshare tumor type and deterministically chooses one of ten templates. Do not report the oracle condition as a generic-prompt result.
