Redistributor: Transforming Empirical Data Distributions

1 code implementation • 25 Oct 2022 • Pavol Harar, Dennis Elbrächter, Monika Dörfler, Kory D. Johnson

We present an algorithm and package, Redistributor, which forces a collection of scalar samples to follow a desired distribution.

Learning Complex Basis Functions for Invariant Representations of Audio

1 code implementation • 13 Jul 2019 • Stefan Lattner, Monika Dörfler, Andreas Arzt

Mapping signals onto complex basis functions learned by the CAE results in a transformation-invariant "magnitude space" and a transformation-variant "phase space".

Improving Machine Hearing on Limited Data Sets

2 code implementations • 21 Mar 2019 • Pavol Harar, Roswitha Bammer, Anna Breger, Monika Dörfler, Zdenek Smekal

In this contribution we investigate how input and target representations interplay with the amount of available training data in a music information retrieval setting.

On orthogonal projections for dimension reduction and applications in augmented target loss functions for learning problems

1 code implementation • 22 Jan 2019 • Anna Breger, Jose Ignacio Orlando, Pavol Harar, Monika Dörfler, Sophie Klimscha, Christoph Grechenig, Bianca S. Gerendas, Ursula Schmidt-Erfurth, Martin Ehler

In two supervised learning problems, clinical image segmentation and music information classification, the application of our proposed augmented target loss functions increase the accuracy.
