Concept-Based Techniques for "Musicologist-friendly" Explanations in a Deep Music Classifier

no code implementations26 Aug 2022 Francesco Foscarin, Katharina Hoedt, Verena Praher, Arthur Flexer, Gerhard Widmer

Current approaches for explaining deep learning systems applied to musical data provide results in a low-level feature space, e. g., by highlighting potentially relevant time-frequency bins in a spectrogram or time-pitch bins in a piano roll.

Defending a Music Recommender Against Hubness-Based Adversarial Attacks

1 code implementation24 May 2022 Katharina Hoedt, Arthur Flexer, Gerhard Widmer

Adversarial attacks can drastically degrade performance of recommenders and other machine learning systems, resulting in an increased demand for defence mechanisms.

On the Veracity of Local, Model-agnostic Explanations in Audio Classification: Targeted Investigations with Adversarial Examples

1 code implementation19 Jul 2021 Verena Praher, Katharina Prinz, Arthur Flexer, Gerhard Widmer

The basic idea is to identify a small set of human-understandable features of the classified example that are most influential on the classifier's prediction.

Audio Classification

The Impact of Label Noise on a Music Tagger

no code implementations14 Aug 2020 Katharina Prinz, Arthur Flexer, Gerhard Widmer

We explore how much can be learned from noisy labels in audio music tagging.

Music Tagging

End-to-End Adversarial White Box Attacks on Music Instrument Classification

no code implementations29 Jul 2020 Katharina Prinz, Arthur Flexer

Small adversarial perturbations of input data are able to drastically change performance of machine learning systems, thereby challenging the validity of such systems.

BIG-bench Machine Learning General Classification

scikit-hubness: Hubness Reduction and Approximate Neighbor Search

1 code implementation2 Dec 2019 Roman Feldbauer, Thomas Rattei, Arthur Flexer

Users will find all functionality of the scikit-learn neighbors package, plus additional support for transparent hubness reduction and approximate nearest neighbor search.

Clustering Retrieval

Basic Filters for Convolutional Neural Networks Applied to Music: Training or Design?

no code implementations7 Sep 2017 Monika Doerfler, Thomas Grill, Roswitha Bammer, Arthur Flexer

The theoretical results show that approximately reproducing mel-spectrogram coefficients by applying adaptive filters and subsequent time-averaging is in principle possible.
