Unsupervised learning-based structural analysis: Search for a characteristic low-dimensional space by local structures in atomistic simulations
TL;DR: In this paper, an unsupervised machine learning method is proposed to analyze the local structure around a target atom, which uses the two-step locality preserving projections (TS-LPP) to find a low-dimensional space wherein the distributions of datapoints for each atom or groups of atoms can be properly captured.
The CONQUEST code: large scale and linear scaling DFT
TL;DR: DFT code CONQUEST, designed from the beginning to enable extremely large-scale calculations on massively parallel platforms, implementing both exact and linear scaling solvers for the ground state, demonstrates essentially perfect weak scaling.

Linear-scaling implementation of exact exchange using localized numerical orbitals and contraction reduction integrals
TL;DR: A numerical method is introduced which avoids the explicit calculation the four-center two-electron repulsion integrals and reduces the prefactor scaling by a factor N, where N is the number of atoms within the range of the exact exchange Hamiltonian.
