Supervised Classification Methods for Flash X-ray single particle diffraction Imagingcs.CV

Two supervised methods classify single-molecule patterns from X-ray imaging.

problem Classifying high-quality patterns from noisy, stochastic XFEL data.
method Supervised template-based learning methods: Eigen-Image and Log-Likelihood classifiers.

Machine learning applied to single-shot x-ray diagnostics in an XFELphysics.data-an

X-ray free-electron lasers (XFELs) are the only sources currently able to produce bright few-fs pulses with tunable photon energies from 100 eV to more than 10 keV. Due to the stochastic SASE operating principles and other technical issues the output pulses are subject to large fluctuations, making it necessary to char…
