In the Euclidean setting, our results imply a quantitative version of Kidger and Lyons (2020)'s approximation theorem and a data-dependent version of Yarotsky and Zhevnerchuk (2019)'s uncursed approximation rates.Anastasis KratsiosLéonie PaponJournal...
文本是教程"The Universal Approximation Theorem for neural networks" by Michael Nielsen 的笔记。 Universal approximation theorem 为什么MLP可以拟合任意的函数? 我们考虑一个最简单的神经网络,最后一层是sigmoid函数: 事实上这就是一个线性函数,然后经过sigmoid扭曲为一条曲线,显然,b决定了不同截距,从而导致sigmoid位...
This universal approximation theorem of operators is suggestive of the structure and potential of deep neural networks (DNNs) in learning continuous operators or complex systems from streams of scattered data. Here, we thus extend this theorem to DNNs. We design a new network with small ...

The activation \({\mathbf{\sigma }} = \frac{{\mathbf{K}}}{{i\left( {\omega - {\mathbf{\Omega }}} \right) + {\mathbf{\Gamma }}}\) is a rational function (see Supplementary Note I) and satisfies the conditions for the universal approximation theorem of neural networks:62 the fun...
Model discovery is a balance between complexity and accuracy The universal approximation theorem states that a neural network with a single hidden layer—with a sufficient number of nodes and appropriate activation functions—can approximate any continuous function on a compact subset of its domain to ...
An application to continuous-time deep residual networks is included. Introduction Weierstrass approximation theorem states that every real-valued continuous map of a compact interval can be C0 approximated by polynomials. The Stone-Weirestrass theorem extends this conclusion to compact Hausdorff space, ...
Deep Learning: “Multilayer feedforward networks are universal approximators” (Hornik, 1989) 10 Theorem 2.5 Exact approximation of functions on a finite set in R 1 Let {x 1 , ..., x n } be a set of distinct points in R r and let g : R r −→R be an arbitrary function. If...
