GP prediction across compositions. a GP performed in composition space, for hysteresis loops captured at 30 °C. The measurements are plotted as filled circles, with the color corresponding to the voltage at which the piezoresponse measurement was acquired. Solid black lines indicate the mean from the GP regression, and blue regions indicate the variance estimates (1 s.d.). b Comparison of predicted response with the measured response. The predicted mean for this composition is plotted as a solid blue line, with measurements (and 1 s.d.) of this composition plotted as filled circles. The shaded blue regions indicate the variance estimates from GP. The measurements fall within 1 s.d. of the blue bounded regions, confirming the validity of the approach
