Convergence of the alternating split Bregman algorithm in infinite-dimensional Hilbert spaces
Amir Moradifam, Adrian Nachman
We prove results on weak convergence for the alternating split Bregman algorithm in infinite dimensional Hilbert spaces. We also show convergence of an approximate split Bregman al…
