ExoAtom: A Database of Atomic Spectra in ExoMol Format
Qing-He Ni, Rujia Wang, Tianyang Xie +4
We present the ExoAtom database, www.exomol.com/exoatom, an extension of the ExoMol database to provide atomic line lists in the ExoMol format. ExoAtom is designed for detailed ast…
Distributionally robust self-supervised learning for tabular data
Shantanu Ghosh, Tiankang Xie, Mikhail Kuznetsov
Machine learning (ML) models trained using Empirical Risk Minimization (ERM) often exhibit systematic errors on specific subpopulations of tabular data, known as error slices. Lear…
Exciton-based sensing of remote electron correlations in 2D heterostructures
Tobias M. R. Wolf, Tian Xie, Chenhao Jin +1
Many monolayer transition metal dichalcogenides, including MoS, MoSe, WS, and WSe, are direct bandgap two-dimensional (2D) semiconductors with sharp optical resonan…
ECGN: A Cluster-Aware Approach to Graph Neural Networks for Imbalanced Classification
Bishal Thapaliya, Anh Nguyen, Yao Lu +7
Classifying nodes in a graph is a common problem. The ideal classifier must adapt to any imbalances in the class distribution. It must also use information in the clustering struct…
