Extending linear growth functionals to functions of bounded fractional variation
Hidde Schönberger
In this paper we consider the minimization of a novel class of fractional linear growth functionals involving the Riesz fractional gradient. These functionals lack the coercivity p…
Approximation of the number of descendants in branching processes
Anton A Kutsenko
We discuss approximations of the relative limit densities of descendants in Galton--Watson processes that follow from the Karlin--McGregor near-constancy phenomena. These approxima…
Banach gradient flows for various families of knot energies
Hannes Matt, Daniel Steenebrügge, Heiko von der Mosel
We establish long-time existence of Banach gradient flows for generalised integral Menger curvatures and tangent-point energies, and for O'Hara's self-repulsive potentials $E^{α,p}…
A note on exponential Riesz bases
Andrei Caragea, Dae Gwan Lee
We prove that if , , are disjoint intervals in with the property that the numbers are l…
Small random initialization is akin to spectral learning: Optimization and generalization guarantees for overparameterized low-rank matrix reconstruction
Dominik Stöger, Mahdi Soltanolkotabi
Recently there has been significant theoretical progress on understanding the convergence and generalization of gradient-based methods on nonconvex losses with overparameterized mo…
Structural Sparsity in Multiple Measurements
Florian Boßmann, Sara Krause-Solberg, Johannes Maly +1
We propose a novel sparsity model for distributed compressed sensing in the multiple measurement vectors (MMV) setting. Our model extends the concept of row-sparsity to allow more…
