-Firmly Nonexpansive Operators on Metric Spaces
Arian Bërdëllima, Florian Lauster, D. Russell Luke
We extend to -uniformly convex spaces tools from the analysis of fixed point iterations in linear spaces. This study is restricted to an appropriate generalization of single-val…
Efficient orbital imaging based on ultrafast momentum microscopy and sparsity-driven phase retrieval
G. S. M. Jansen, M. Keunecke, M. Düvel +8
We present energy-resolved photoelectron momentum maps for orbital tomography that have been collected with a novel and efficient time-of-flight momentum microscopy setup. This set…
Convergence Analysis of the Relaxed Douglas-Rachford Algorithm
D. Russell Luke, Anna-Lena Martins
Motivated by nonconvex, inconsistent feasibility problems in imaging, the relaxed alternating averaged reflections algorithm, or relaxed Douglas-Rachford algorithm (DR), was fir…
Optimization on Spheres: Models and Proximal Algorithms with Computational Performance Comparisons
D. Russell Luke, Shoham Sabach, Marc Teboulle
We present a unified treatment of the abstract problem of finding the best approximation between a cone and spheres in the image of affine transformations. Prominent instances of t…
Random Function Iterations for Consistent Stochastic Feasibility
Neal Hermer, D. Russell Luke, Anja Sturm
We study the convergence of stochastic fixed point iterations in the consistent case (in the sense of Butnariu and Flåm (1995)) in several different settings, under decreasingly re…
Characterizations of Super-regularity and its Variants
Aris Daniilidis, D. Russell Luke, Matthew K. Tam
Convergence of projection-based methods for nonconvex set feasibility problems has been established for sets with ever weaker regularity assumptions. What has not kept pace with th…
