Abstract X-ray absorption near-edge structure (XANES) spectra are the fingerprint of the local atomic and electronic structures around the absorbing atom. However, the quantitative analysis of these spectra is not straightforward. Even with the most

In this paper, we develop a new technique for quantitative analysis of the near region of X-ray absorption spectra that is based on the extraction of spectrum descriptors and machine learning. The use of descriptors (edge position, intensity and curv
