Figure 7. Parity plots indicating the prediction performance exhibited on the test set, containing 20% of total data, for the thermophysical properties: (A) density by ; (B) thermal conductivity by ; and (C) specific heat by . The predicted and true properties are reported on the Y- and X- axes respectively. The red circles indicate the GP mean and the blue bars correspond to the ±2σ bands. The relative L₂ error norm and number of points within the 95% CI are also reported on each plot.
