Public Datasets#

The pnpl.datasets package provides dataset classes designed for deep learning workflows (PyTorch Dataset).

GroupedDataset#

Utility dataset to group multiple datasets and expose a unified interface.

from pnpl.datasets import GroupedDataset, LibriBrainSpeech, LibriBrainPhoneme

HDF5Dataset (base)#

pnpl.datasets.hdf5.HDF5Dataset is a simple base for datasets backed by MEG signals serialized as HDF5, with standardization and slicing support.

Key features:

  • windowed access (channels, time)

  • channel-wise standardization

  • optional clipping

LibriBrain 2025#

  • LibriBrainPhoneme: phoneme classification from MEG segments.

  • LibriBrainSpeech: speech/silence time-series labels over a window.

Both rely on a BIDS-like directory structure and can download needed files from Hugging Face.
