Schubert varieties and distances between subspaces of different dimensions
We resolve a basic problem on subspace distances that often arises in applications: How
can the usual Grassmann distance between equidimensional subspaces be extended to …

On the expressive power of deep polynomial neural networks
We study deep neural networks with polynomial activations, particularly their expressive
power. For a fixed architecture and activation degree, a polynomial neural network defines …

Learning algebraic varieties from samples
We seek to determine a real algebraic variety from a fixed finite subset of points. Existing
methods are studied and new methods are developed. Our focus lies on aspects of topology …

Theoretical and numerical analysis of 3d reconstruction using point and line incidences
We study the joint image of lines incident to points, meaning the set of image tuples obtained
from fixed cameras observing a varying 3D point-line incidence. We prove a formula for the …

Line multiview varieties
We present an algebraic study of line correspondences for pinhole cameras, in contrast to
the thoroughly studied point correspondences. We define the line multiview variety as the …
