[18a-A401-4] Gigapixel Imaging XAFS data analysis by using machine learning
Keywords:XAFS, Machine learning
Imaging XAFS realizes a high resolution and an ultra-wide field of view simultaneously. We obtained X-ray absorption spectra (XAFS) in the field of view of the centimeter scale with spatial resolution on the nanometer scale. In this study, we developed a method to classify spectra, and we analyzed 450 million spectra by using this method. As a result, we succeeded in finding a new chemical state that had been missed using conventional methods.
