We now illustrate the influence of the experimental noise on the predictions produced by the fGP-DRT model. The hyperparameters were obtained by maximizing the experimental evidence at specified noise levels, 𝜎 𝑛 exp . Panels (a), (d), and (g) of Figure show the Nyquist plots corresponding to 𝜎 𝑛 exp = 1.0, 2.0, and 3.0 Ω, respectively. As 𝜎 𝑛 exp increases, the recovered DRT has larger credible bands around the mean, indicating greater uncertainty, see panels (b), (e), and
