mne_denoise.dss.RobustTanhDenoiser

class mne_denoise.dss.RobustTanhDenoiser(alpha: float = 1.0)

Residual hyperbolic-tangent nonlinearity.

The transform is source - tanh(alpha * source).

Parameters:

alphafloat, default=1.0

Tanh scale.

denoise(source: ndarray) → ndarray

Apply the robust hyperbolic-tangent nonlinearity.

Parameters:

sourcendarray, shape (n_times,) or (n_times, n_epochs)

Source time series.

Returns:

denoisedndarray, same shape as source

source - tanh(alpha * source).
