mne.decoding.get_coef

mne.decoding.get_coef(estimator, attr='filters_', inverse_transform=False)

Retrieve the coefficients of an estimator ending with a Linear Model.

This is typically useful to retrieve “spatial filters” or “spatial patterns” of decoding models 1.

Parameters

estimatorobject | None

An estimator from scikit-learn.

attrstr

The name of the coefficient attribute to retrieve, typically 'filters_' (default) or 'patterns_'.

inverse_transformbool

If True, returns the coefficients after inverse transforming them with the transformer steps of the estimator.

Returns

coefarray

The coefficients.
