Quadratic neural networks for solving inverse problems
Leon Frischauf, Otmar Scherzer, Cong Shi
In this paper we investigate the solution of inverse problems with neural network ansatz functions with generalized decision functions. The relevant observation for this work is th…

Analysis of Generalized Iteratively Regularized Landweber Iterations driven by data
Andrea Aspri, Otmar Scherzer
We investigate generalized versions of the Iteratively Regularized Landweber Method, initially introduced in [Appl. Math. Optim., 38(1):45-68, 1998], to address linear and nonlinea…

Uncertainty Quantification for Scale-Space Blob Detection
Fabian Parzer, Clemens Kirisits, Otmar Scherzer
We consider the problem of blob detection for uncertain images, such as images that have to be inferred from noisy measurements. Extending recent work motivated by astronomical app…
