Off-the-grid data-driven optimization of sampling schemes in MRI
Alban Gossard, Frédéric de Gournay, Pierre Weiss
We propose a novel learning based algorithm to generate efficient and physically plausible sampling patterns in MRI. This method has a few advantages compared to recent learning ba…

Fast Wavelet Decomposition of Linear Operators through Product-Convolution Expansions
Paul Escande, Pierre Weiss
Wavelet decompositions of integral operators have proven their efficiency in reducing computing times for many problems, ranging from the simulation of waves or fluids to the resol…

Sampling Rates for -Synthesis
Maximilian März, Claire Boyer, Jonas Kahn +1
This work investigates the problem of signal recovery from undersampled noisy sub-Gaussian measurements under the assumption of a synthesis-based sparsity model. Solving the $\ell^…
