Solving the 3D High-Frequency Helmholtz Equation using Contour Integration and Polynomial Preconditioning
Xiao Liu, Yuanzhe Xi, Yousef Saad +1
We propose an iterative solution method for the 3D high-frequency Helmholtz equation that exploits a contour integral formulation of spectral projectors. In this framework, the sol…

Random mesh projectors for inverse problems
Sidharth Gupta, Konik Kothari, Maarten V. de Hoop +1
We propose a new learning-based approach to solve ill-posed inverse problems in imaging. We address the case where ground truth training samples are rare and the problem is severel…
