Fig. 5: Convergence of the results as a function of the number of snapshots used for training.
From: Predicting electronic screening for fast Koopmans spectral functional calculations
The top panel shows the mean absolute error in the eigenvalues, while the bottom panel shows the band gap. To get a statistical average, both quantities were obtained for 10 test snapshots. The dotted line indicates the mean, while the shaded region is the standard deviation across the 10 test snapshots.
