Neural network approximation

R DeVore, B Hanin, G Petrova - Acta Numerica, 2021 - cambridge.org
Neural networks (NNs) are the method of choice for building learning algorithms. They are
now being investigated for other numerical tasks such as solving high-dimensional partial …

hp-VPINNs: Variational physics-informed neural networks with domain decomposition

E Kharazmi, Z Zhang, GE Karniadakis - Computer Methods in Applied …, 2021 - Elsevier
We formulate a general framework for hp-variational physics-informed neural networks (hp-
VPINNs) based on the nonlinear approximation of shallow and deep neural networks and …

Model reduction and neural networks for parametric PDEs

K Bhattacharya, B Hosseini, NB Kovachki… - The SMAI journal of …, 2021 - numdam.org
We develop a general framework for data-driven approximation of input-output maps
between infinitedimensional spaces. The proposed approach is motivated by the recent …

Universal approximation with deep narrow networks

P Kidger, T Lyons - Conference on learning theory, 2020 - proceedings.mlr.press
Abstract The classical Universal Approximation Theorem holds for neural networks of
arbitrary width and bounded depth. Here we consider the natural 'dual'scenario for networks …
