A sparse Kaczmarz solver and a linearized Bregman method for online compressed sensing
Dirk A. Lorenz, Stephan Wenger, Frank Schöpfer +1
An algorithmic framework to compute sparse or minimal-TV solutions of linear systems is proposed. The framework includes both the Kaczmarz method and the linearized Bregman method…
The Linearized Bregman Method via Split Feasibility Problems: Analysis and Generalizations
Dirk A. Lorenz, Frank Schöpfer, Stephan Wenger
The linearized Bregman method is a method to calculate sparse solutions to systems of linear equations. We formulate this problem as a split feasibility problem, propose an algorit…
Interactive Visualization and Simulation of Astronomical Nebulae
Stephan Wenger, Marco Ament, Wolfgang Steffen +3
Interactive visualization and simulation of astrophysical phenomena help astronomers and enable digital planetariums and television documentaries to take their spectators on a jour…
Shape: A 3D Modeling Tool for Astrophysics
Wolfgang Steffen, Nicholas Koning, Stephan Wenger +2
We present a flexible interactive 3D morpho-kinematical modeling application for astrophysics. Compared to other systems, our application reduces the restrictions on the physical a…
