Fig. 2(Color online) Confusion matrices of Random Forest models trained on: (a--c) spectra at high-symmetry points, (d--f) spectra on the band paths shown in
. The strains are (a),(d)
a/a0=1.00 (unstrained), (b),(e)
a/a0=0.95, and (c),(f)
a/a0=1.05. The colors represent the accuracy, calculated as the ratio of the matrix elements to the sum of each row.
