I will also highlight the potential of machine learning to predict characteristic structural features in nanocrystals just from their 3D Bragg coherent diffraction patterns [6] %G English %2 https://cea.hal.science/cea-04066378/document %2 https://cea.hal.science/cea-04066378/file/a61263.pdf %L cea-04066378 %U https://cea.hal.science/cea-04066378 %~ CEA %~ UGA %~ UNIV-TLN %~ CNRS %~ UNIV-AMU %~ INPG %~ NEEL %~ IM2NP %~ NEEL-CRG %~ IRIG %~ CEA-GRE %~ UGA-EPE %~ NEEL-TECHNO
