| # 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. | |
