Reinforcement Learning Based Power Grid Day-Ahead Planning and AI-Assisted Control

no code implementations15 Feb 2023 Anton R. Fuxjäger, Kristian Kozak, Matthias Dorfer, Patrick M. Blies, Marcel Wasserer

The ongoing transition to renewable energy is increasing the share of fluctuating power sources like wind and solar, raising power grid volatility and making grid operation increasingly complex and costly.

Power Grid Congestion Management via Topology Optimization with AlphaZero

1 code implementation10 Nov 2022 Matthias Dorfer, Anton R. Fuxjäger, Kristian Kozak, Patrick M. Blies, Marcel Wasserer

Unfortunately, redispatching of fossil generators leads to excessive grid operation costs and higher emissions, which is in direct opposition to the decarbonization of the energy sector.

The Receptive Field as a Regularizer in Deep Convolutional Neural Networks for Acoustic Scene Classification

3 code implementations3 Jul 2019 Khaled Koutini, Hamid Eghbal-zadeh, Matthias Dorfer, Gerhard Widmer

To this end, we analyse the receptive field (RF) of these CNNs and demonstrate the importance of the RF to the generalization capability of the models.

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.

Cross-Modal Music Retrieval and Applications: An Overview of Key Methodologies

no code implementations12 Feb 2019 Meinard Müller, Andreas Arzt, Stefan Balke, Matthias Dorfer, Gerhard Widmer

There has been a rapid growth of digitally available music data, including audio recordings, digitized images of sheet music, album covers and liner notes, and video clips.

Attention as a Perspective for Learning Tempo-invariant Audio Queries

no code implementations15 Sep 2018 Matthias Dorfer, Jan Hajič jr., Gerhard Widmer

Current models for audio--sheet music retrieval via multimodal embedding space learning use convolutional neural networks with a fixed-size window for the input audio.

Learning to Listen, Read, and Follow: Score Following as a Reinforcement Learning Game

1 code implementation17 Jul 2018 Matthias Dorfer, Florian Henkel, Gerhard Widmer

Score following is the process of tracking a musical performance (audio) with respect to a known symbolic representation (a score).

Deep Within-Class Covariance Analysis for Robust Audio Representation Learning

no code implementations10 Nov 2017 Hamid Eghbal-zadeh, Matthias Dorfer, Gerhard Widmer

To tackle this problem, we propose Deep Within-Class Covariance Analysis (DWCCA), a deep neural network layer that significantly reduces the within-class covariance of a DNN's representation, improving performance on unseen test data from a shifted distribution.

On the Potential of Simple Framewise Approaches to Piano Transcription

2 code implementations15 Dec 2016 Rainer Kelz, Matthias Dorfer, Filip Korzeniowski, Sebastian Böck, Andreas Arzt, Gerhard Widmer

In an attempt at exploring the limitations of simple approaches to the task of piano transcription (as usually defined in MIR), we conduct an in-depth analysis of neural network-based framewise transcription.

Towards End-to-End Audio-Sheet-Music Retrieval

no code implementations15 Dec 2016 Matthias Dorfer, Andreas Arzt, Gerhard Widmer

This paper demonstrates the feasibility of learning to retrieve short snippets of sheet music (images) when given a short query excerpt of music (audio) -- and vice versa --, without any symbolic representation of music or scores.

Towards Score Following in Sheet Music Images

no code implementations15 Dec 2016 Matthias Dorfer, Andreas Arzt, Gerhard Widmer

This paper addresses the matching of short music audio snippets to the corresponding pixel location in images of sheet music.
