Convergence analysis of deep Ritz method with over-parameterization

Neural Networks
The deep Ritz method (DRM) has recently been shown to be a simple and effective method for solving PDEs. However, the numerical analysis of DRM is still incomplete, especially why over-parameterized DRM works remains unknown. This paper presents the first convergence analysis of the over-parameterized DRM for second-order elliptic equations with Robin ...

Free vibration analysis of deep doubly curved open shells using the Ritz method

Aerospace Science and Technology, 2017
Abstract This paper develops a unified semi-analytical method for the free vibration analysis of moderately thick doubly curved open shells with arbitrary geometry and classic boundary conditions. The only restriction on the shell's geometry is that boundaries are being coincided by the principal curvature lines of the shell. The formulation is based

Analysis of Deep Ritz Methods for Semilinear Elliptic Equations

Numerical Mathematics: Theory, Methods and Applications
Summary: In this paper, we propose a method for solving semilinear elliptical equations using a ResNet with ReLU\(^2\) activations. Firstly, we present a comprehensive formulation based on the penalized variational form of the elliptical equations. We then apply the Deep Ritz Method, which works for a wide range of equations.
