Towards Robust and Truly Large-Scale Audio-Sheet Music Retrieval

no code implementations21 Sep 2023 Luis Carvalho, Gerhard Widmer

A range of applications of multi-modal music information retrieval is centred around the problem of connecting large collections of sheet music (images) to corresponding audio recordings, that is, identifying pairs of audio and score excerpts that refer to the same musical content.

Self-Supervised Contrastive Learning for Robust Audio-Sheet Music Retrieval Systems

no code implementations21 Sep 2023 Luis Carvalho, Tobias Washüttl, Gerhard Widmer

We then conclude by arguing for the potential of self-supervised contrastive learning for alleviating the annotated data scarcity in multi-modal music retrieval models.

Soft-SVM Regression For Binary Classification

no code implementations24 May 2022 Man Huang, Luis Carvalho

In this work, we introduce a new exponential family based on a convex relaxation of the hinge loss function using softness and class-separation parameters.

Deviance Matrix Factorization

no code implementations12 Oct 2021 Liang Wang, Luis Carvalho

We investigate a general matrix factorization for deviance-based data losses, extending the ubiquitous singular value decomposition beyond squared error loss.

Exploiting Temporal Dependencies for Cross-Modal Music Piece Identification

no code implementations26 May 2021 Luis Carvalho, Gerhard Widmer

This paper addresses the problem of cross-modal musical piece identification and retrieval: finding the appropriate recording(s) from a database given a sheet music query, and vice versa, working directly with audio and scanned sheet music images.

Learning Soft-Attention Models for Tempo-invariant Audio-Sheet Music Retrieval

no code implementations26 Jun 2019 Stefan Balke, Matthias Dorfer, Luis Carvalho, Andreas Arzt, Gerhard Widmer

Quantitative and qualitative results on synthesized piano data indicate that this attention increases the robustness of the retrieval system by focusing on different parts of the input representation based on the tempo of the audio.
