"description": "TCGA lower-grade glioma three-class classification, with 247 distinct patients. CNV (5,000), mRNA (3,435) and miRNA (102) features and targets are retained from MLOmics. DNA methylation is reconstructed from TCGA/Xena HumanMethylation450 by verified CpG identifiers and primary-tumour patient barcodes: 4,705 of the 5,000 original probes are assayed; the 295 unassayed probes are excluded. Missing beta values remain missing for fold-fitted imputation. Existing five outer folds and three-fold inner CV are retained. Patient identifiers are metadata, never features.",
