Graph Partitioning and Sparse Matrix Ordering using Reinforcement Learning and Graph Neural Networks

1 code implementation8 Apr 2021 Alice Gatti, Zhixiong Hu, Tess Smidt, Esmond G. Ng, Pieter Ghysels

The partitioning quality is compared with partitions obtained using METIS and SCOTCH, and the nested dissection ordering is evaluated in the sparse solver SuperLU.

Deep learning: Extrapolation tool for ab initio nuclear theory

no code implementations6 Oct 2018 Gianina Alina Negoita, James P. Vary, Glenn R. Luecke, Pieter Maris, Andrey M. Shirokov, Ik Jae Shin, Youngman Kim, Esmond G. Ng, Chao Yang, Matthew Lockner, Gurpur M. Prabhu

The NCSM and other approaches require an extrapolation of the results obtained in a finite basis space to the infinite basis space limit and assessment of the uncertainty of those extrapolations.

Deep Learning: A Tool for Computational Nuclear Physics

no code implementations8 Mar 2018 Gianina Alina Negoita, Glenn R. Luecke, James P. Vary, Pieter Maris, Andrey M. Shirokov, Ik Jae Shin, Youngman Kim, Esmond G. Ng, Chao Yang

In recent years, several successful applications of the Artificial Neural Networks (ANNs) have emerged in nuclear physics and high-energy physics, as well as in biology, chemistry, meteorology, and other fields of science.
