The dual approach to non-negative super-resolution: perturbation analysis and data fidelity
Stéphane Chrétien, Andrew Thompson, Bogdan Toader
We study the problem of super-resolution, where we recover the locations and weights of non-negative point sources from (potentially noisy) samples of their convolution with a Gaus…

On the subdifferential of symmetric convex functions of the spectrum for symmetric and orthogonally decomposable tensors
Stéphane Chrétien, Tianwen Wei
The subdifferential of convex functions of the singular spectrum of real matrices has been widely studied in matrix analysis, optimization and automatic control theory. Convex opti…
