Data Distillation for Neural Network Potentials toward Foundational Dataset

no code implementations9 Nov 2023 Gang Seob Jung, SangKeun Lee, Jong Youl Choi

Furthermore, the data can be translated to other metallic systems (aluminum and niobium), without repeating the sampling and distillation processes.

Scalable training of graph convolutional neural networks for fast and accurate predictions of HOMO-LUMO gap in molecules

no code implementations22 Jul 2022 Jong Youl Choi, Pei Zhang, Kshitij Mehta, Andrew Blanchard, Massimiliano Lupo Pasini

Graph Convolutional Neural Network (GCNN) is a popular class of deep learning (DL) models in material science to predict material properties from the graph representation of molecular structures.

Multi-task graph neural networks for simultaneous prediction of global and atomic properties in ferromagnetic systems

1 code implementation4 Feb 2022 Massimiliano Lupo Pasini, Pei Zhang, Samuel Temple Reeve, Jong Youl Choi

We train HydraGNN on an open-source ab initio density functional theory (DFT) dataset for iron-platinum (FePt) with a fixed body centered tetragonal (BCT) lattice structure and fixed volume to simultaneously predict the mixing enthalpy (a global feature of the system), the atomic charge transfer, and the atomic magnetic moment across configurations that span the entire compositional range.
