This week, guys from Ufa University of Science and Technology and Southern Federal University came to visit us! The undergraduates of our laboratory conducted a training course for the guests. During the lectures, students got acquainted with popular machine-learning interatomic potentials and learned what ideas lie behind training of moment tensor potentials. During the practical classes, guests got the skills of working with our MLIP package, and at the end of the course, the potentials on the lattice for high-entropy alloys will be analyzed.
