Fig. 4: Illustration of an unrolled model prediction versus the high-fidelity reference solution, initialized at time t0 for a test trajectory.

The microstructural states of a polarization (\({{\mathcal{P}}}_{x}\)) and b electrostatic potential (\({\mathcal{V}}\)) are depicted at the initial (t0) and final (t100) times. The prediction and high-fidelity trajectories for both variables are visualized in the low-dimensional space, utilizing the first three principal components.
