| "description": "Three-class histological grade (1, 2, 3) from primary breast-tumour gene expression in METABRIC: 1,892 distinct patients and 20,603 released expression measurements. Exclude 88 expression-profiled patients without a recorded grade. Use only the supplied log2 microarray intensities, preserving 13 missing cells for training-fitted imputation. Clinical annotations and patient/sample IDs are not features. This is a retrospective tumour molecular/pathology task. Preserve source feature-row identity even when gene annotations repeat. Use a patient-disjoint, grade-stratified 70/15/15 split (1,324/284/284); fit any additional preprocessing only on training rows.", |
