On the linear convergence rates of exchange and continuous methods for total variation minimization
Axel Flinth, Frédéric de Gournay, Pierre Weiss
We analyze an exchange algorithm for the numerical solution total-variation regularized inverse problems over the space M() of Radon measures on a subset of R d. Our main re…

Estimation of Angles of Arrival Through Superresolution -- A Soft Recovery Approach for General Antenna Geometries
Mahdi Barzegar, Guiseppe Caire, Axel Flinth +3
The estimation of direction of arrivals with help of -minimization is studied. Contrary to prior work in this direction, which has only considered certain antenna placement des…
