Unsupervised Machine Learning Discovery of Chemical and Physical Transformation Pathways from Imaging Data

1 code implementation19 Oct 2020 Sergei V. Kalinin, Ondrej Dyck, Ayana Ghosh, Bobby G. Sumpter, Maxim Ziatdinov

We show that unsupervised machine learning can be used to learn physical and chemical transformation pathways from the observational microscopic data, as demonstrated for atomically resolved images in Scanning Transmission Electron Microscopy (STEM) and ferroelectric domain structures in Piezoresponse Force Microscopy (PFM).
