Convergence of gradient flow for learning convolutional neural networks

Jona-Maria Diederen, Holger Rauhut, Ulrich Terstiege

Convolutional neural networks are widely used in imaging and image recognition. Learning such networks from training data leads to the minimization of a non-convex function. This m…

Convergence of gradient descent for learning linear neural networks

Gabin Maxime Nguegnang, Holger Rauhut, Ulrich Terstiege

We study the convergence properties of gradient descent for training deep linear neural networks, i.e., deep matrix factorizations, by extending a previous analysis for the related…

Learning deep linear neural networks: Riemannian gradient flows and convergence to global minimizers

Bubacarr Bah, Holger Rauhut, Ulrich Terstiege +1

We study the convergence of gradient flows related to learning deep linear neural networks (where the activation function is the identity map) from data. In this case, the composit…

Low-rank matrix recovery via rank one tight frame measurements

Holger Rauhut, Ulrich Terstiege

The task of reconstructing a low rank matrix from incomplete linear measurements arises in areas such as machine learning, quantum state tomography and in the phase retrieval probl…

Stable low-rank matrix recovery via null space properties

Maryia Kabanava, Richard Kueng, Holger Rauhut +1

The problem of recovering a matrix of low rank from an incomplete and possibly noisy set of linear measurements arises in a number of areas. In order to derive rigorous recovery re…

Low rank matrix recovery from rank one measurements

Richard Kueng, Holger Rauhut, Ulrich Terstiege

We study the recovery of Hermitian low rank matrices from undersampled measurements via nuclear norm minimization. We consider the particular scenar…

The supersingular locus of the Shimura variety for GU(1,n-1) over a ramified prime

Michael Rapoport, Ulrich Terstiege, Sean Wilson

We analyze the geometry of the supersingular locus of the reduction modulo p of a Shimura variety associated to a unitary similitude group GU(1,n-1) over Q, in the case that p is r…

On the regularity of special difference divisors

Ulrich Terstiege

In this note we prove that the difference divisors associated with special cycles on unitary Rapoport-Zink spaces of signature (1,n-1) in the unramified case are always regular.

On the Arithmetic Fundamental Lemma in the minuscule case

Michael Rapoport, Ulrich Terstiege, Wei Zhang

The arithmetic fundamental lemma conjecture of the third author connects the derivative of an orbital integral on a symmetric space with an intersection number on a formal moduli s…

Intersections of special cycles on the Shimura variety for GU(1,2)

Ulrich Terstiege

We establish a close connection between intersection multiplicities of special cycles on arithmetic models of the Shimura variety for GU(1,2) and Fourier coefficients of derivative…

Intersections of arithmetic Hirzebruch-Zagier cycles

Ulrich Terstiege

We establish a close connection between the intersection multiplicity of three arithmetic Hirzebruch-Zagier cycles and the Fourier coefficients of the derivative of a certain Siege…

Antispecial cycles on the Drinfeld upper half plane and degenerate Hirzebruch-Zagier cycles

Ulrich Terstiege

We define the notion of antispecial cycles on the Drinfeld upper half plane in analogy to the notion of special cycles defined by Kudla and Rapoport in their Inventiones paper. We…
