Schematic diagram of the workflow using UMAP to analyze a raw nanoXRD data set. (a) Schematic diagram of data acquisition in nanoXRD. (b) Each diffraction image corresponds to a specific angular position ω and sampling point i, as shown in panel (a), during the online experiment. For each diffraction image, the horizontal size p and vertical size q correspond to the angular range in the 2θ and φ directions, respectively. (c) Diffraction patterns from point i are transformed to a vector, the dimensions of which are determined by the size of the diffraction patterns. Similar processes are repeated for N sampling points. The data set prepared in (c) is fed into (d) the UMAP algorithm, which is (e) further embedded and clustered in a 2D space for visualization.
