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.

Neural networks: deep, shallow, or in between?
Guergana Petrova, Przemyslaw Wojtaszczyk
We give estimates from below for the error of approximation of a compact subset from a Banach space by the outputs of feed-forward neural networks with width W, depth l and Lipschi…

Greedy Algorithms for Reduced Bases in Banach Spaces
Ronald DeVore, Guergana Petrova, Przemyslaw Wojtaszczyk
Given a Banach space X and one of its compact sets F, we consider the problem of finding a good n dimensional space X_n \subset X which can be used to approximate the elements of F…
