Graph Regularized Sparse Semi-Nonnegative Matrix Factorization for Data Reduction
Anthony Rhodes, Bin Jiang, Jenny Jiang
Non-negative Matrix Factorization (NMF) is an effective algorithm for multivariate data analysis, including applications to feature selection, pattern recognition, and computer vis…
Intrinsic mixed finite element methods for linear Cosserat elasticity
Andrea Dziubek, Kaibo Hu, Michael Karow +1
We propose two parameter-robust mixed finite element methods for linear Cosserat elasticity. The Cosserat coupling constant , connecting the displacement and rotation vect…
Scalable Multilevel Monte Carlo Methods Exploiting Parallel Redistribution on Coarse Levels
Hillary R. Fairbanks, Delyan Z. Kalchev, Chak Shing Lee +1
We study an element agglomeration coarsening strategy that requires data redistribution at coarse levels when the number of coarse elements becomes smaller than the used computatio…
Matrix-free GPU-accelerated saddle-point solvers for high-order problems in
Will Pazner, Tzanio Kolev, Panayot Vassilevski
This work describes the development of matrix-free GPU-accelerated solvers for high-order finite element problems in . The solvers are applicable to grad-div and D…
The Hellan-Herrmann-Johnson and TDNNS method for linear and nonlinear shells
Michael Neunteufel, Joachim Schöberl
In this paper we extend the recently introduced mixed Hellan-Herrmann-Johnson (HHJ) method for nonlinear Koiter shells to nonlinear Naghdi shells by means of a hierarchical approac…
Analysis of curvature approximations via covariant curl and incompatibility for Regge metrics
Jay Gopalakrishnan, Michael Neunteufel, Joachim Schöberl +1
The metric tensor of a Riemannian manifold can be approximated using Regge finite elements and such approximations can be used to compute approximations to the Gauss curvature and…
