YAML Metadata Warning:empty or missing yaml metadata in repo card

Check out the documentation for more information.

demo_dataset

This repository contains a curated collection of processed EEG benchmark datasets packaged for model training and evaluation.

Each dataset is stored in its own directory and follows a consistent split-based HDF5 layout:

  • train.h5
  • val.h5
  • test.h5
  • croissant.json
  • croissant_manifest.csv
  • metadata_summary.json

Repository structure

Each dataset directory contains:

  • train.h5, val.h5, test.h5
    • HDF5 files containing the packaged split data.
    • In most datasets, X stores EEG tensors and y stores labels.
    • Some blind-test releases may omit y in specific splits.
  • croissant.json
    • Dataset-level Croissant metadata for discoverability and validation.
  • croissant_manifest.csv
    • Split-level manifest describing file names, sample counts, channel counts, and timepoints.
  • metadata_summary.json
    • Compact summary of task type, label vocabulary, channel count, sampling rate, window length, and split sizes.

Data format

For a typical split file:

  • X.shape = (n_samples, n_channels, n_timepoints)
  • y.shape = (n_samples,) when labels are available

The exact sampling rate, window length, and channel count differ by dataset and are documented in:

  • metadata_summary.json
  • croissant.json

Metadata policy

The packaged metadata intentionally avoids internal mount paths, usernames, and local infrastructure identifiers.

Where possible, provenance in croissant.json points to public references such as:

  • original dataset papers
  • official dataset release pages
  • PhysioNet / OpenNeuro / institutional dataset pages

Notes

  • This repository is a processed benchmark collection, not a raw-data release.
  • Temporal segmentation is dataset-specific and is not forced to be uniform across all datasets.
  • Some datasets in the same family may use different window lengths if their benchmark packaging differs.
  • For exact task definitions, label mappings, and window parameters, use metadata_summary.json.

Recommended usage

  1. Read metadata_summary.json before training on a dataset.
  2. Use croissant_manifest.csv to inspect split sizes and basic tensor dimensions.
  3. Use croissant.json if you need machine-readable dataset metadata or want to run Croissant validation.
