Polynomial-Time Amoeba Neighborhood Membership and Faster Localized Solving
Eleanor Anthony, Sheridan Grant, Peter Gritzmann +1
We derive efficient algorithms for coarse approximation of algebraic hypersurfaces, useful for estimating the distance between an input polynomial zero set and a given query point.…
A balanced k-means algorithm for weighted point sets
Steffen Borgwardt, Andreas Brieden, Peter Gritzmann
The classical -means algorithm for partitioning points in into clusters is one of the most popular and widely spread clustering methods. The need to respe…
3D particle tracking velocimetry using dynamic discrete tomography
Andreas Alpers, Peter Gritzmann, Dmitry Moseev +1
Particle tracking velocimetry in 3D is becoming an increasingly important imaging tool in the study of fluid dynamics, combustion as well as plasmas. We introduce a dynamic discret…
