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.
