spectf

Part of TabBioMed (TabBioMed: A Large-Scale Benchmark for Biomedical Tabular Learning), a benchmark of 94 curated biomedical tabular datasets. Code, preprocessing and documentation: https://github.com/AI-sandbox/TabBioMed.

Normal (0; 55) versus abnormal (1; 212) cardiac SPECT, using 44 supplied rest/stress image summaries per patient. Remove 82 redundant PMLB copies; the 267 retained records exactly match the corrected UCI train/test union. Pool that cohort for benchmark CV rather than using the UCI 80/187 split. Use five stratified outer folds and three inner folds; fit imputation, encoding and scaling within training partitions.

Domain Task Samples Features Classes
Clinical & Healthcare binary 267 44 2

Splits. 5 stored outer cross-validation folds (data/fold_<i>/), each with train/val/test files (fold 0: 186/27/54 rows). Every row appears in exactly one outer test fold. HPO in the paper uses inner folds drawn from each outer non-test pool.

Files

  • data/**.parquet: one row per sample. row_idx is the row index in the original TabBioMed array; f_<i>[_<name>] are the features (in order); target (or target_<j> for multi-target tasks) is the label. Categorical feature indices (0-based, among the features): []. Missing values are stored as nulls.
  • metadata.json: TabBioMed task metadata (task type, categorical indices, source, description).
  • feature_names.json: original feature names, in column order.
  • sample_metadata.csv: per-row provenance (identifiers, source annotations); not features.
