Efficient wide-field radio interferometry response
Philipp Arras, Martin Reinecke, Rüdiger Westermann +1
Radio interferometers do not measure the sky brightness distribution directly but rather a modified Fourier transform of it. Imaging algorithms, thus, need a computational represen…
Interactive Focus+Context Rendering for Hexahedral Mesh Inspection
Christoph Neuhauser, Junpeng Wang, Rüdiger Westermann
The visual inspection of a hexahedral mesh with respect to element quality is difficult due to clutter and occlusions that are produced when rendering all element faces or their ed…
A comparative study of convolutional neural network models for wind field downscaling
Kevin Höhlein, Michael Kern, Timothy Hewson +1
We analyze the applicability of convolutional neural network (CNN) architectures for downscaling of short-range forecasts of near-surface winds on extended spatial domains. Short-r…
Comparison of classical and Bayesian imaging in radio interferometry
Philipp Arras, Hertzog L. Bester, Richard A. Perley +4
CLEAN, the commonly employed imaging algorithm in radio interferometry, suffers from a number of shortcomings: in its basic version it does not have the concept of diffuse flux, an…
Visual Analysis of Multi-Parameter Distributions across Ensembles
Alexander Kumpf, Josef Stumpfegger, Patrick Fabian Härtl +1
For an ensemble of data points in a multi-parameter space, we present a visual analytics technique to select a representative distribution of parameter values, and analyse how repr…
Inverting the Feature Visualization Process for Feedforward Neural Networks
Christian Reinbold, Rüdiger Westermann
This work sheds light on the invertibility of feature visualization in neural networks. Since the input that is generated by feature visualization using activation maximization doe…
