Fig. 5: NMF and STRETCHEDNMF solutions on simulated PXRD data with 2% expansions on ZnSe.

From: Stretched non-negative matrix factorization

Fig. 5

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