eelbrain.dss

eelbrain.dss(ndvar)

Denoising source separation (DSS)

Parameters

ndvar (NDVar (case, dim, time)) – Data to decompose. DSS is performed over the case and time dimensions.

Return type

(<class ‘eelbrain._data_obj.NDVar’>, <class ‘eelbrain._data_obj.NDVar’>)

Returns

• to_dss (NDVar (dss, dim)) – Transform data to DSS.

• from_dss (NDVar (dim, dss)) – Reconstruct data form DSS.

Notes

the method is described in 1. This function uses the implementation from the mne-sandbox.
