Sparse Recovery from Group Orbits
Timm Gilles, Hartmut Führ
While most existing sparse recovery results allow only minimal structure within the measurement scheme, many practical problems possess significant structure. To address this gap,…
Energy Propagation in Scattering Convolution Networks Can Be Arbitrarily Slow
Hartmut Führ, Max Getter
We analyze energy decay for deep convolutional neural networks employed as feature extractors, including Mallat's wavelet scattering transform. For time-frequency scattering transf…
Dilational Symmetries of Decomposition and Coorbit Spaces
Hartmut Führ, Reihaneh Raisi Tousi
We investigate the invariance properties of general wavelet coorbit spaces and Besov-type decomposition spaces under dilations by matrices. We show that these matrices can be chara…
Embeddings of anisotropic Besov spaces into Sobolev spaces
David Bartusel, Hartmut Führ
We study the embeddings of (homogeneous and inhomogeneous) anisotropic Besov spaces associated to an expansive matrix into Sobolev spaces, with focus on the influence of on…
Embeddings of shearlet coorbit spaces into Sobolev spaces
Hartmut Führ, René Koch
We investigate the existence of embeddings of shearlet coorbit spaces associated to weighted mixed -spaces into classical Sobolev spaces in dimension three by using the descri…
System bandwidth and the existence of generalized shift-invariant frames
Hartmut Führ, Jakob Lemvig
We consider the question whether, given a countable system of lattices in a locally compact abelian group , there exists a sequence of functions $(g_j)_{j \in…
