It is widely known that neural networks (NNs) are universal approximators of continuous functions. However, a less known but powerful result is that a NN with a single hidden layer can accurately approximate any nonlinear continuous operator. This universal approximation theorem of operators is sugges...

In 1989, George Cybenko provided the first proof of the Universal Approximation Theorem, which states that a neural network with a single hidden layer is theoretically capable of modeling any problem. This was remarkable because it meant that neural networks could (at least in theory) outdo any ...
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...
We formulate the approximation of operators by composition of a class of linear integral operators and nonlinear activation functions, so that the composed operator can approximate complex nonlinear operators. We prove a universal approximation theorem for our construction. Furthermore, we introduce four ...

(Mathematics) a mathematical theorem that gives the expansion of any binomial raised to a positive integral power,n. It containsn+ 1 terms: (x+a)n=xn+nxn–1a+ [n(n–1)/2]xn–2a2+…+ (nk)xn–kak+ … +an, where (nk) =n!/(n–k)!k!, the number of combinations ofkitems se...
According to the Universal Approximation Theorem, properly weighted and biased feed-forward ANN architectures can approximate any continuous function with precision and accuracy, depending on the number of hidden units available [36,37]. This remarkable ability for universal approximation is a result of...
This function guarantees the universal approximation capability of SLFNs under any learning algorithm, such as the ELM [10,20]. Throughout the manuscript, the input weights and biases are generated from the range [−1,1][−1,1] based on uniform distribution [24,41]. For each subcarrier...
