Proximal gradient methods in Banach spaces
Gerd Wachsmuth, Daniel Walter
Proximal gradient methods are a popular tool for the solution of structured, nonsmooth minimization problems. In this work, we investigate an extension of the former to general Ban…

Lazifying point insertion algorithms in spaces of measures
Arsen Hnatiuk, Daniel Walter
Greedy point insertion algorithms have emerged as an attractive tool for the solution of minimization problems over the space of Radon measures. Conceptually, these methods can be…
