“…This idea to combine multiple ML models is called stacking 46 . Aguiar et al 32 , 33 reports that stacking improves the prediction accuracy for space group determination by electron diffraction. However, for our case, stacking did not improve the performance, i.e., the prediction performance was deteriorated.…”

“…Application of ML and related techniques for diffraction data analysis is a hot research topic in recent times 13 , 14 . Among various subtopics such as pattern decomposition and phase identification 15 18 cluster analysis and phase mapping 19 23 , similarity metrics for comparison of diffraction data 24 26 classification of a crystal symmetry 27 33 , a paper by Park et al 34 is relevant to this work. Park et al classified crystal systems and space groups by applying a convolutional neural network (CNN) to simulated powder XRD patterns.…”

“…Because the data were largely inconclusive when compared to known phases, a peak-to-peak correspondence with all known materials was computed using the latest trained neural network model for crystallography, reported by Aguiar et al in Figure 34. 4,5 Based on the results of combining multiple peaks and combinations across all known crystallographic chemistries, the cubic structure is indexed at the highest significance amongst the crystal families. Within cubic, there is a high probability reported in Figure 34c to classify within cubic to space group Fm3m, #225.…”

“…Liu et al 21 refined atomic pair distribution functions in a convolutional neural network (CNN) to classify SGs. For similar purposes, Park et al 22 , Vecsei et al 23 , Wang et al 24 , Oviedo et al 25 , and Aguiar et al 26 used powder X-ray diffraction (XRD) 1D curves, for which information such as peak positions, intensities, and fullwidths at half-maximum are mainly treated as the key input descriptors. In addition, Ziletti et al 27 (in a parent work of this study), Aguiar et al 28 , Kaufmann et al 29 , and Ziatdinov et al 30 developed DL models by extracting features from electron-beam based 2D DPs.…”
