EEG Dataset

This dataset was created using braindecode, a library for deep learning with EEG/MEG/ECoG signals.

Dataset Information

Property Value
Number of recordings 1
Dataset type Windowed (from Epochs object)
Number of channels 26
Sampling frequency 250 Hz
Number of windows / samples 48
Total size 0.03 MB
Storage format zarr

Usage

To load this dataset::

.. code-block:: python

    from braindecode.datasets import BaseConcatDataset

    # Load dataset from Hugging Face Hub
    dataset = BaseConcatDataset.pull_from_hub("username/dataset-name")

    # Access data
    X, y, metainfo = dataset[0]
    # X: EEG data (n_channels, n_times)
    # y: label/target
    # metainfo: window indices

Using with PyTorch DataLoader

::

from torch.utils.data import DataLoader

# Create DataLoader for training
train_loader = DataLoader(
    dataset,
    batch_size=32,
    shuffle=True,
    num_workers=4
)

# Training loop
for X, y, metainfo in train_loader:
    # X shape: [batch_size, n_channels, n_times]
    # y shape: [batch_size]
    # metainfo shape: [batch_size, 2] (start and end indices)
    # Process your batch...

Dataset Format

This dataset is stored in Zarr format, optimized for:

  • Fast random access during training (critical for PyTorch DataLoader)
  • Efficient compression with blosc
  • Cloud-native storage compatibility
