Figure 9.

Histograms of $error/ϵ$ for models trained on vorticity data with non-periodic boundary conditions. $error$ is the model error given by (24) (with $i=L$) and $ϵ$ is given by (35). There were $359\times 279=\mathrm{100,161}$ total models trained. The count on the vertical axis is the number of models that fell into the corresponding bin.
