On the infinite-dimensional QR algorithm
Abstract: Spectral computations of infinite-dimensional operators are notoriously difficult, yet ubiquitous in the sciences. Indeed, despite more than half a century of research, it is still unknown which classes of operators...
The difficulty of computing stable and accurate neural networks
Deep learning (DL) has had unprecedented success and is now entering
scientific computing with full force. However, current DL methods typically
suffer from instability, even when universal approximation properties guarantee
