• Title: Towards Explaining Expressive Qualities in Piano Recordings: Transfer of Explanatory Features via Acoustic Domain Adaptation
• Authors: Shreyan Chowdhury and Gerhard Widmer
• Abstract summary: In this work, we show that by utilising unsupervised domain adaptation together with receptive-field regularised deep neural networks, it is possible to significantly improve generalisation to this domain. We demonstrate that our domain-adapted models can better predict and explain expressive qualities in classical piano performances, as perceived and described by human listeners.

• Abstract: Emotion and expressivity in music have been topics of considerable interest in the field of music information retrieval. In recent years, mid-level perceptual features have been suggested as means to explain computational predictions of musical emotion. We find that the diversity of musical styles and genres in the available dataset for learning these features is not sufficient for models to generalise well to specialised acoustic domains such as solo piano music. In this work, we show that by utilising unsupervised domain adaptation together with receptive-field regularised deep neural networks, it is possible to significantly improve generalisation to this domain. Additionally, we demonstrate that our domain-adapted models can better predict and explain expressive qualities in classical piano performances, as perceived and described by human listeners.

Unlike acoustic features with clear physical meaning, these embeddings lack clear interpretability. This paper proposes a modified probing approach to explain deep learning embeddings in the speech emotion space.

  We are inspired by how musicians compose music not just from a movie script, but also through visualizations. We propose MeLFusion, a model that can effectively use cues from a textual description and the corresponding image to synthesize music. Our exhaustive experimental evaluation suggests that adding visual information to the music synthesis pipeline significantly improves the quality of generated music.

  Music emotion recognition is an important task in MIR (Music Information Retrieval) research. One important step towards better models would be to understand what a model is actually learning from the data. We show how to derive explanations of model predictions in terms of spectrogram image segments that connect to the high-level emotion prediction.

  The role of musical prosody remains under-explored despite several studies demonstrating a strong connection between prosody and emotion. In this study, we restrict the input of traditional machine learning algorithms to the features of musical prosody. We utilize a methodology for individual data collection from vocalists, and personal ground truth labeling by the artist themselves.
