Accelerating Variance-Reduced Stochastic Gradient Methods

Derek Driggs, Matthias J. Ehrhardt, Carola-Bibiane Schönlieb

Variance reduction is a crucial tool for improving the slow convergence of stochastic gradient descent. Only a few variance-reduced methods, however, have yet been shown to directl…

Learning the Sampling Pattern for MRI

Ferdia Sherry, Martin Benning, Juan Carlos De los Reyes +5

The discovery of the theory of compressed sensing brought the realisation that many inverse problems can be solved even when measurements are "incomplete". This is particularly int…

Deep learning as optimal control problems: models and numerical methods

Martin Benning, Elena Celledoni, Matthias J. Ehrhardt +2

We consider recent work of Haber and Ruthotto 2017 and Chang et al. 2018, where deep learning neural networks have been interpreted as discretisations of an optimal control problem…
