Weighted variation spaces and approximation by shallow ReLU networks
Ronald DeVore, Robert D. Nowak, Rahul Parhi +1
We investigate the approximation of functions on a bounded domain by the outputs of single-hidden-layer ReLU neural networks of width . This form of…

A note on best n-term approximation for generalized Wiener classes
Ronald DeVore, Guergana Petrova, Przemyslaw Wojtaszczyk
We determine the best n-term approximation of generalized Wiener model classes in a Hilbert space . This theory is then applied to several special cases.
