# FL-MedClsBench — Representative Sample

**Beyond Synthetic Splits: A Benchmark for Federated Learning on Real-World Medical Data Classification**

This is a **representative sample** of the full [FL-MedClsBench](https://huggingface.co/datasets/FL-MedClsBench/FL-MedClsBench) dataset (>14 GB).

---

## Sampling Methodology

- **Images**: 5 samples randomly selected per client (seed=42)
- **FL-BCa** (3D NIfTI MRI): 2 volumes per center
- **FL-ECG** (HDF5 ECG signals): full dataset included (~7 GB, 3 files)
- **Metadata**: All CSV split files (train/val/test × 3 seeds) included in full
