Fig. 6

Extracted components compared to the ground-truth components for powder PXRD patterns with 2% and 1% expansions, computed from the structures of BaTiO3 (blue curve in a, c, and e) and ZnSe (blue curve in b, d, and f). Extracted signals done with conventional NMF (red curves in a and b), stretchedNMF (red curves in c and d) and sparse-stretchedNMF (red curves in e and f).
