Fast convergence of inertial dynamics with Hessian-driven damping under geometry assumptions

Jean-François Aujol, Charles Dossal, Văn Hào Hoàng +2

First-order optimization algorithms can be considered as a discretization of ordinary differential equations (ODEs) \cite{su2014differential}. In this perspective, studying the pro…

Fast off-the-grid sparse recovery with over-parametrized projected gradient descent

Pierre-Jean Bénard, Yann Traonmilin, Jean-François Aujol

We consider the problem of recovering off-the-grid spikes from Fourier measurements. Successful methods such as sliding Frank-Wolfe and continuous orthogonal matching pursuit (OMP)…
