braindecode.samplers.SequenceSampler

class braindecode.samplers.SequenceSampler(metadata, n_windows, n_windows_stride, random_state=None)

Sample sequences of consecutive windows.

Parameters

• metadata (pd.DataFrame) – See RecordingSampler.

• n_windows (int) – Number of consecutive windows in a sequence.

• n_windows_stride (int) – Number of windows between two consecutive sequences.

• random_state (np.random.RandomState | int | None) – Random state.

info

See RecordingSampler.

Type

pd.DataFrame

file_ids

Array of shape (n_sequences,) that indicates from which file each sequence comes from. Useful e.g. to do self-ensembling.

Type

np.ndarray of ints
