Structural Robustness of Complex Networks: A Survey of A Posteriori Measures[Feature] [PDF]
IEEE Circuits and Systems Magazine, 2023 Network robustness is critical for various industrial and social networks against malicious attacks, which has various meanings in different research contexts and here it refers to the ability of a network to sustain its functionality when a fraction of ...

A Posteriori Learning for Quasi‐Geostrophic Turbulence Parametrization [PDF]
Journal of Advances in Modeling Earth Systems, 2022 The use of machine learning to build subgrid parametrizations for climate models is receiving growing attention. State‐of‐the‐art strategies address the problem as a supervised learning task and optimize algorithms that predict subgrid fluxes based on ...

Stable a posteriori LES of 2D turbulence using convolutional neural networks: Backscattering analysis and generalization to higher Re via transfer learning [PDF]
Journal of Computational Physics, 2021 There is a growing interest in developing data-driven subgrid-scale (SGS) models for large-eddy simulation (LES) using machine learning (ML). In a priori (offline) tests, some recent studies have found ML-based data-driven SGS models that are trained on ...

A posteriori error bounds for discontinuous Galerkin methods for quasilinear parabolic problems [PDF]
, 2009 We derive a posteriori error bounds for a quasilinear parabolic problem, which is approximated by the $hp$-version interior penalty discontinuous Galerkin method (IPDG). The error is measured in the energy norm.

Residual based a posteriori error estimation for Dirichlet boundary control problems [PDF]
ESAIM: Proceedings and Surveys, 2021 We study a residual–based a posteriori error estimate for the solution of Dirichlet boundary control problem governed by a convection diffusion equation on a two dimensional convex polygonal domain, using the local discontinuous Galerkin (LDG) method ...

A posteriori error estimates for the virtual element method [PDF]
Numerische Mathematik, 2016 An posteriori error analysis for the virtual element method (VEM) applied to general elliptic problems is presented. The resulting error estimator is of residual-type and applies on very general polygonal/polyhedral meshes.

A posteriori error estimates for a Virtual Element Method for the Steklov eigenvalue problem [PDF]
Computers and Mathematics with Applications, 2016 The paper deals with the a posteriori error analysis of a virtual element method for the Steklov eigenvalue problem. The virtual element method has the advantage of using general polygonal meshes, which allows implementing very efficiently mesh ...
