mne_features.bivariate.compute_nonlin_interdep¶

mne_features.bivariate.compute_nonlin_interdep(data, tau=2, emb=10, nn=5, include_diag=False)¶

Measure of nonlinear interdependence.

Parameters

datandarray, shape (n_channels, n_times)

The signals.

tauint (default: 2)

Delay in time samples.

embint (default: 10)

Embedding dimension.

nnint (default: 5)

Number of Nearest Neighbors.

include_diagbool (default: False)

If False, features corresponding to pairs of identical electrodes are not computed. In other words, features are not computed from pairs of electrodes of the form (ch[i], ch[i]).

Returns

outputndarray, shape (n_output,)

With n_output = n_channels * (n_channels + 1) / 2 if include_diag is True and n_output = n_channels * (n_channels - 1) / 2 if include_diag is False.

Notes

Alias of the feature function: nonlin_interdep. See [1] and [2].
