CTSpinoPelvic1K Sample

This is a 10-case stratified sample of the parent CTSpinoPelvic1K dataset, intended for interface inspection and reproducibility checks. It is NOT large enough for any segmentation training or meaningful evaluation.

Sampling provenance

• Pruned from: anonymous-neurips-ED/CTSpinoPelvic1K-Sample (in place)
• Random seed: 42
• Strategy: stratified by lstv_class (≥1 case per non-empty class)
• Records kept: 10 of 1153
• lstv_class distribution: {3: 1, 0: 7, 2: 1, 1: 1}
• config distribution: {'pelvic_native': 5, 'spine_only': 2, 'fused': 3}

Splits caveat

splits_5fold.json is preserved for surviving tokens but folds may be sparse or empty. Do not run cross-validation on the sample; use the parent dataset for that.
