braindecode.preprocessing.preprocess#
- braindecode.preprocessing.preprocess(concat_ds, preprocessors, save_dir=None, overwrite=False, n_jobs=None, offset=0, copy_data=None)[source]#
Apply preprocessors to a concat dataset.
- Parameters:
concat_ds (BaseConcatDataset) – A concat of
BaseDataset
orWindowsDataset
to be preprocessed.preprocessors (list of Preprocessor) – Preprocessor objects to apply to each dataset.
save_dir (str | None) – If provided, save preprocessed data under this directory and reload datasets in
concat_ds
withpreload=False
.overwrite (bool) – When
save_dir
is provided, controls whether to delete the old subdirectories that will be written to undersave_dir
. If False and the corresponding subdirectories already exist, aFileExistsError
is raised.n_jobs (int | None) – Number of jobs for parallel execution. See
joblib.Parallel
for details.offset (int) – Integer added to the dataset id in the concat. Useful when processing and saving very large datasets in chunks to preserve original positions.
copy_data (bool | None) – Whether the data passed to parallel jobs should be copied or passed by reference.
- Returns:
Preprocessed dataset.
- Return type:
