Figure 4
(a) Box plots of the absolute errors for 242 measured reflectivity curves for each of the three predicted parameters. The upper and lower edges of the boxes represent the first and third quartiles, respectively, with the horizontal lines inside the boxes denoting the medians. The pink boxes represent the error compared with the pure neural network predictions. The blue boxes represent the error after applying a simple least-mean-squares minimization using the neural network predictions as starting parameters. The green boxes show the error when a qz shift optimization was performed before this fit. (b) The same box plots of the median error but as a percentage of the ground truth.
