MetaDetect: Uncertainty Quantification and Prediction Quality Estimates for Object Detection
Marius Schubert, Karsten Kahl, Matthias Rottmann
In object detection with deep neural networks, the box-wise objectness score tends to be overconfident, sometimes even indicating high confidence in presence of inaccurate predicti…
Coarsening in Algebraic Multigrid using Gaussian Processes
Hanno Gottschalk, Karsten Kahl
Multigrid methods have proven to be an invaluable tool to efficiently solve large sparse linear systems arising in the discretization of partial differential equations (PDEs). Alge…
A multigrid accelerated eigensolver for the Hermitian Wilson-Dirac operator in lattice QCD
Andreas Frommer, Karsten Kahl, Francesco Knechtli +3
Eigenvalues of the Hermitian Wilson-Dirac operator are of special interest in several lattice QCD simulations, e.g., for noise reduction when evaluating all-to-all propagators. In…
On the equivalence of the Hermitian eigenvalue problem and hypergraph edge elimination
Karsten Kahl, Bruno Lang
It is customary to identify sparse matrices with the corresponding adjacency or incidence graph. For the solution of linear systems of equations using Gaussian elimination, the rep…
