Approximation properties of operator coorbit spaces and sparsity classes
Monika Dörfler, Lukas Köhldorfer, Franz Luef +1
Extensions of coorbit spaces for functions to operators have been introduced by two different groups in \cite{doelumcskr24} and \cite{köbaLOC25}, where one is based on the coorbit…
Signal Analysis using Born-Jordan-type Distribution
Elena Cordero, Maurice de Gosson, Monika Dörfler +1
In this note we exhibit recent advances in signal analysis via time-frequency distributions. New members of the Cohen class, generalizing the Wigner distribution, reveal to be effe…
Learning Complex Basis Functions for Invariant Representations of Audio
Stefan Lattner, Monika Dörfler, Andreas Arzt
Learning features from data has shown to be more successful than using hand-crafted features for many machine learning tasks. In music information retrieval (MIR), features learned…
Multi-Window Weaving Frames
Monika Dörfler, Markus Faulhuber
In this work we deal with the recently introduced concept of weaving frames. We extend the concept to include multi-window frames and present the first sufficient criteria for a fa…
Time-Frequency Partitions and Characterizations of Modulation Spaces with Localization Opertors
Monika Doerfler, Karlheinz Groechenig
We study families of time-frequency localization operators and derive a new characterization of modulation spaces. This characterization relates the size of the localization operat…
Compactness Criteria in Function Spaces
Monika Dörfler, Hans G. Feichtinger, Karlheinz Gröchenig
The classical criterion for compactness in Banach spaces of functions can be reformulated into a simple tightness condition in the time-frequency domain. This description preserves…
