Fig. 10: Uncertainty quantification for Si0.4Ge0.6 system.

a ML prediction of the electron density, b Epistemic Uncertainty c Aleatoric Uncertainty d Total Uncertainty shown along the dotted line from the ML prediction slice. The uncertainty represents the bound ± 3σtotal, where, σtotal is the total uncertainty. The unit for electron density is e Bohr−3, where e denotes the electronic charge.
