Comparison of wMSD for our data-driving algorithm vs. linear baseline interpolation algorithms. For each line type, the red (blue) line shows driving at Δt = 20 (50)δt. The solid curves reproduce the SVD-based CHAR-DDBC results from Figure 8, for reference; the dashed curves show the difference metric for SVD CHAR-DDBC when no information is known about either the density ρ or internal energy density ϵ, and the dotted curves show the metric when B and v are linearly interpolated while ρ and ϵ are held fixed to their initial values. Panel (a) gives wMSD calculated in the driving boundary layer, i.e., the k = 100 (k = 0) cell in the GT (Data-Driven) simulation. (b) Same as (a) but 15 cells higher into the simulation, i.e., the layer from Figure 7.
