sc_muraro_celltype

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.

Classify eight released human pancreas cell-type annotations from Muraro et al. CEL-Seq2 expression; exclude the three epsilon cells.

Domain	Task	Samples	Features	Classes
Single-cell	classification	2,119	18,508	8

Splits. Fixed train/val/test split (1483/318/318 rows).

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.
feature_metadata.csv: per-feature annotations.
