# EEG Dataset
This dataset was created using [braindecode](https://braindecode.org), a library for deep learning with EEG/MEG/ECoG signals.
## Dataset Information
- **Number of recordings**: 1
- **Number of channels**: 26
- **Sampling frequency**: 250.0 Hz
- **Data type**: Windowed (from Epochs object)
- **Number of windows**: 48
- **Total size**: 0.04 MB
- **Storage format**: zarr
## Usage
To load this dataset:
```python
from braindecode.datasets import BaseConcatDataset
# Load dataset from Hugging Face Hub
dataset = BaseConcatDataset.from_pretrained("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
```python
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, _ in train_loader:
# X shape: [batch_size, n_channels, n_times]
# y shape: [batch_size]
# 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
