摘要
Electron,optical,and scanning probe microscopy methods are generating ever increasing volume of image data containing information on atomic and mesoscale structures and functionalities.This necessitates the development of themachine learning methods for discovery of physical and chemical phenomena from the data,such as manifestations of symmetry breaking phenomena in electron and scanning tunneling microscopy images,or variability of the nanoparticles.Variational autoencoders(VAEs)are emerging as a powerful paradigm for the unsupervised data analysis,allowing to disentangle the factors of variability and discover optimal parsimonious representation.Here,we summarize recent developments in VAEs,covering the basic principles and intuition behind the VAEs.
