Figure 4From: Estimation of diffusion coefficients from voltammetric signals by support vector and gaussian process regressionDistributions of absolute errors on a logarithmic scale for estimated diffusion coefficients in cm2 s-1 on the test data sets for simulations for EC, E qr , and E qr C mechanisms. Black horizontal bars indicate the mean of the error distributions. The SVR and GPR algorithms used PCA preprocessing.Back to article page
