Universal Architectures for the Learning of Polyhedral Norms and Convex Regularization Functionals arXiv:2503.19190v1 Announce Type: new Abstract: This paper addresses the task of learning convex regularizers to guide the reconstruction of images from limited data. By imposing that the reconstruction be amplitude-equivariant, we narrow down the class of admissible functionals to those that can be…
