Redistributor: Transforming Empirical Data Distributions
Pavol Harar, Dennis Elbrächter, Monika Dörfler +1
We present an algorithm and package, Redistributor, which forces a collection of scalar samples to follow a desired distribution. When given independent and identically distributed…
On orthogonal projections for dimension reduction and applications in augmented target loss functions for learning problems
Anna Breger, Jose Ignacio Orlando, Pavol Harar +6
The use of orthogonal projections on high-dimensional input and target data in learning frameworks is studied. First, we investigate the relations between two standard objectives i…
Generalized Born--Jordan Distributions and Applications
Elena Cordero, Maurice de Gosson, Monika Dörfler +1
The quadratic nature of the Wigner distribution causes the appearance of unwanted interferences. This is the reason why engineers, mathematicians and physicists look for related ti…
Basic Filters for Convolutional Neural Networks Applied to Music: Training or Design?
Monika Doerfler, Thomas Grill, Roswitha Bammer +1
When convolutional neural networks are used to tackle learning problems based on music or, more generally, time series data, raw one-dimensional data are commonly pre-processed to…
A Phase Vocoder based on Nonstationary Gabor Frames
Emil Solsbæk Ottosen, Monika Dörfler
We propose a new algorithm for time stretching music signals based on the theory of nonstationary Gabor frames (NSGFs). The algorithm extends the techniques of the classical phase…
Nonstationary Gabor Frames - Approximately Dual Frames and Reconstruction Errors
Monika Dörfler, Ewa Matusiak
Nonstationary Gabor frames, recently introduced in adaptive signal analysis, represent a natural generalization of classical Gabor frames by allowing for adaptivity of windows and…
Frames adapted to a phase-space cover
Monika Dörfler, José Luis Romero
We construct frames adapted to a given cover of the time-frequency or time-scale plane. The main feature is that we allow for quite general and possibly irregular covers. The frame…
Quilted Gabor frames - a new concept for adaptive time-frequency representation
Monika Doerfler
Certain signal classes such as audio signals call for signal representations with the ability to adapt to the signal's properties. In this article we introduce the new concept of q…
Representation of operators in the time-frequency domain and generalized Gabor multipliers
Monika Dorfler, Bruno Torresani
Starting from a general operator representation in the time-frequency domain, this paper addresses the problem of approximating linear operators by operators that are diagonal or b…
