mne.decoding.TimeDelayingRidge¶

class mne.decoding.TimeDelayingRidge(tmin, tmax, sfreq, alpha=0.0, reg_type='ridge', fit_intercept=True, n_jobs=1, edge_correction=True)[source]¶

Ridge regression of data with time delays.

Parameters

tminint | float: The starting lag, in seconds (or samples if sfreq == 1). Negative values correspond to times in the past.
tmaxint | float: The ending lag, in seconds (or samples if sfreq == 1). Positive values correspond to times in the future. Must be >= tmin.
sfreqfloat: The sampling frequency used to convert times into samples.
alphafloat: The ridge (or laplacian) regularization factor.
reg_typestr | list: Can be “ridge” (default) or “laplacian”. Can also be a 2-element list specifying how to regularize in time and across adjacent features.
fit_interceptbool: If True (default), the sample mean is removed before fitting.
n_jobsint | str: The number of jobs to use. Can be an int (default 1) or 'cuda'.

New in version 0.18.
edge_correctionbool: If True (default), correct the autocorrelation coefficients for non-zero delays for the fact that fewer samples are available. Disabling this speeds up performance at the cost of accuracy depending on the relationship between epoch length and model duration. Only used if estimator is float or None.

New in version 0.18.

Notes

This class is meant to be used with mne.decoding.ReceptiveField by only implicitly doing the time delaying. For reasonable receptive field and input signal sizes, it should be more CPU and memory efficient by using frequency-domain methods (FFTs) to compute the auto- and cross-correlations.

Methods

`__hash__`(/)	Return hash(self).
`fit`(X, y)	Estimate the coefficients of the linear model.
`get_params`([deep])	Get parameters for this estimator.
`predict`(X)	Predict the output.
`set_params`(**params)	Set the parameters of this estimator.

fit(X, y)[source]¶

Estimate the coefficients of the linear model.

Parameters

Xarray, shape (n_samples[, n_epochs], n_features): The training input samples to estimate the linear coefficients.
yarray, shape (n_samples[, n_epochs], n_outputs): The target values.

Returns

selfinstance of TimeDelayingRidge: Returns the modified instance.

get_params(deep=True)[source]¶

Get parameters for this estimator.

Parameters

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

Returns

paramsdict: Parameter names mapped to their values.

predict(X)[source]¶

Predict the output.

Parameters

Xarray, shape (n_samples[, n_epochs], n_features): The data.

Returns

Xndarray: The predicted response.

set_params(**params)[source]¶

Set the parameters of this estimator.

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