Preprocessing

To download and prepare this dataset, run brainsets prepare kemp_sleep_edf_2013.

Parameters:

  • root (str, optional) – Root directory for the dataset. Defaults to processed_dir from brainsets config.

  • recording_ids (list[str], optional) – List of recording IDs to load.

  • transform (Callable, optional) – Data transformation to apply.

  • uniquify_channel_ids (bool, optional) – Whether to prefix channel IDs with session ID to ensure uniqueness. Defaults to True.

  • fold_number (int, optional) – The cross-validation fold index (0 to 2 for a 3-fold split). Defaults to 0.

  • fold_type (str, optional) – The splitting strategy. Must be one of: - “intrasession”: Epoch-level stratified split within each session. - “intersubject”: Subject-level split (subjects are assigned to train/valid/test). - “intersession”: Session-level split (subject-session pairs are assigned to train/valid/test). Defaults to “intrasession”.

  • dirname (str, optional) – Subdirectory for the dataset. Defaults to “kemp_sleep_edf_2013”.
