class mne.decoding.LinearModel(model=None)[source]#

Compute and store patterns from linear models.

The linear model coefficients (filters) are used to extract discriminant neural sources from the measured data. This class computes the corresponding patterns of these linear filters to make them more interpretable [1].

Parameters:

modelobject | None: A linear model from scikit-learn with a fit method that updates a coef_ attribute. If None the model will be LogisticRegression.

Attributes:

filters_ndarray, shape ([n_targets], n_features): If fit, the filters used to decompose the data.
patterns_ndarray, shape ([n_targets], n_features): If fit, the patterns used to restore M/EEG signals.

Methods

`fit`(X, y, **fit_params)	Estimate the coefficients of the linear model.
`get_metadata_routing`()	Get metadata routing of this object.
`get_params`([deep])	Get parameters for this estimator.
`set_params`(**params)	Set the parameters of this estimator.

fit(X, y, **fit_params)[source]#

Estimate the coefficients of the linear model.

Save the coefficients in the attribute filters_ and computes the attribute patterns_.

Parameters:

Xarray, shape (n_samples, n_features): The training input samples to estimate the linear coefficients.
yarray, shape (n_samples, [n_targets]): The target values.
**fit_paramsdict of str -> object: Parameters to pass to the fit method of the estimator.

Returns:

selfinstance of LinearModel: Returns the modified instance.

get_metadata_routing()[source]#

Get metadata routing of this object.

Please check User Guide on how the routing mechanism works.

Returns:

routingMetadataRequest: A MetadataRequest encapsulating routing information.

get_params(deep=True)[source]#

Get parameters for this estimator.

Parameters:

deepbool, default=True: If True, will return the parameters for this estimator and contained subobjects that are estimators.

Returns:

paramsdict: Parameter names mapped to their values.

set_params(**params)[source]#

Set the parameters of this estimator.

The method works on simple estimators as well as on nested objects (such as Pipeline). The latter have parameters of the form <component>__<parameter> so that it’s possible to update each component of a nested object.

Parameters:

**paramsdict: Estimator parameters.

Returns:

selfestimator instance: Estimator instance.
