Figure 8. Parity plot indicating the prediction performance of 
on the test set for different train-test ratios: (A) 80%:20%; (B) 60%:40%; (C) 40%:60%; and (D) 20%:80%. The predicted melt pool depth (
) is reported on the Y-axis and the true melt pool depth (δ) is on the X-axis. The red circles indicate the GP mean and the blue bars are the ±2σ bands, for each case of the train-test ratio.
