On the Approximation of Rough Functions with Artificial Neural Networks

Tim De Ryck
Deep neural networks and the ENO procedure are both efficient frameworks for approximating rough functions. We prove that at any order, the stencil shifts of the ENO and ENO-SR interpolation procedures can be exactly obtained using a deep ReLU neural network. In addition, we construct and provide error bounds for ReLU neural networks that directly approximate the output of the ENO and ENO- SR interpolation procedures. This surprising fact enables the transfer of several desirable...
