AtomSets -- A Hierarchical Transfer Learning Framework for Small and Large Materials Datasets

1 code implementation4 Feb 2021 Chi Chen, Shyue Ping Ong

Here we leverage the transfer learning concept and the graph network deep learning framework and develop the AtomSets machine learning framework for consistent high model accuracy at both small and large materials data.

Graph Networks as a Universal Machine Learning Framework for Molecules and Crystals

3 code implementations Chem. Mater. 2018 Chi Chen, Weike Ye, Yunxing Zuo, Chen Zheng, Shyue Ping Ong

Similarly, we show that MEGNet models trained on $\sim 60, 000$ crystals in the Materials Project substantially outperform prior ML models in the prediction of the formation energies, band gaps and elastic moduli of crystals, achieving better than DFT accuracy over a much larger data set.

Automated Generation and Ensemble-Learned Matching of X-ray Absorption Spectra

no code implementations6 Nov 2017 Chen Zheng, Kiran Mathew, Chi Chen, Yiming Chen, Hanmei Tang, Alan Dozier, Joshua J. Kas, Fernando D. Vila, John J. Rehr, Louis F. J. Piper, Kristin Persson, Shyue Ping Ong

We report the development of XASdb, a large database of computed reference X-ray absorption spectra (XAS), and a novel Ensemble-Learned Spectra IdEntification (ELSIE) algorithm for the matching of spectra.
