CompMusic Seminar
23 Feb 2017

On February 23rd 2017, Thursday, from 9:30h to 14:00h in room 55.309 of the Communication Campus of the Universitat Pompeu Fabra in Barcelona, we will have a CompMusic seminar. This seminar accompanies the PhD thesis defenses of Gopala Krishna Koduri and Sertan Şentürk that takes place the previous day.

"Con Espressione! - An Update from the Computational Performance Modelling Front"
Computational models of expressive music performance have been a target of considerable research efforts in the past 20 years. Motivated by the desire to gain a deeper understanding of the workings of this complex art, various research groups have proposed different classes of computational models (rule-based, case-based, machine-learning-based) for different parametric dimensions of expressive performance, and it has been demonstrated in various studies that such models can provide interesting new insights into this musical art. In this presentation, I will review recent work that has carried  this research further. I will mostly focus on a general modelling framework known as the "Basis Mixer", and show various extensions of this model that have gradually increased the modelling power of the framework. However, it will also become apparent that are still serious limitations and obstacles on the path to comprehensive models of musical expressivity, and I will briefly report on a new ERC project entitled "Con Espressione", which expressly addresses these challenges. Along the way, we will also hear about a recent musical "Turing Test" that is said to demonstrate that computational performance models have now reached a level where their interpretations of classical piano music are qualitatively indistinguishable from true human performances -- a story that I will quickly try to put into perspective ...

"Digital Musicology with Large Datasets"
The increasing availability of music data as well as networks and computing resources has the potential to profoundly change the methodology of musicological research towards a more data-driven empirical approach. However, many questions are still unanswered regarding the technology, data collection and provision, metadata, analysis methods and legal aspects. This talk will report on an effort to address these questions in the Digital Music Lab project, and present achieved outcomes, lessons learnt and challenges that emerged in this process.

"The explication of musical knowledge through automatic pattern finding"
In this talk I will discuss the role of computational modeling for gaining insights into the specifics of a musical style for which there exists no long-standing music theory such as in Western classical music, Carnatic music or Ottoman-Turkish makam music. Specifically, I address the role of automatic pattern search in enabling us to scrutinize what it is that we really know about a specific music style, if we consider ourselves to be musical experts. I elaborate my hypothesis that musical knowledge is often implicit, while computation enables us to make part of this knowledge explicit and evaluate it on a data set. This talk will address the explication of musical knowledge for the question as to when we perceive two folk melodies to be variants of each other for the case of Dutch and Irish folk songs, and when we consider a piece to be a ragtime. With examples from research within my VIDI-project MUSIVA on patterns in these musical styles, I discuss how musical experts and non-experts working together on developing computational methods can gain important insights into the specifics of a musical style, and the implicit knowledge of musical experts.

"Convergence of Technologies to Connect Audio with Meaning: from Semantic Web Ontologies to Semantic Audio Production”
Science and technology plays in an increasingly vital role in how we experience, how we compose, perform, share and enjoy musical audio. The invention of recording in the late 19th century is a profound example that, for the first time in human history, disconnected music performance from listening and gave rise to a new industry as well as new fields of scientific investigation. But musical experience is not just about listening. Human minds make sense of what we hear by categorising and by making associations, cognitive processes which give rise to meaning or influence our mood. Perhaps the next revolution akin to recording is therefore in audio semantics. Technologies that mimic our abilities and enable interaction with audio on human terms are already changing the way we experience it. The emerging field of Semantic Audio is in the confluence of several key fields, namely, signal processing, machine learning and Semantic Web ontologies that enable knowledge representation and logic-based inference. In my talk, I will put forward that synergies between these fields provide a fruitful way, if not necessary to account for human interpretation of sound. I will outline music and audio related ontologies and ontology based systems that found applications on the Semantic Web, as well as intelligent audio production tools that enable linking musical concepts with signal processing parameters in audio systems. I will outline my recent work demonstrating how web technologies may be used to create interactive performance systems that enable mood-based audience-performer communication and how semantic audio technologies enable us to link social tags and audio features to better understand the relationship between music and emotions. I will hint at how some principles used in my research also contribute to enhancing scientific protocols, ease experimentation and facilitate reproducibility. Finally, I will discuss challenges in fusing audio and semantic technologies and outline some future opportunities they may bring about.

Talks by Dr. Eita Nakamura and Dr. Shinji Sako
15 Nov 2016

Dr. Eita Nakamura (Kyoto University, Japan) and Dr. Shinji Sako (Nagoya Institute of Technology, Japan)
will be giving two talks:

 

"Rhythm Transcription of Piano Performances Based on Hierarchical. Bayesian Modelling of Repetition and Modification of Musical Note Patterns" by Dr. Eita Nakamura. Kyoto University, Japan. (15h Nov, 17:00h. Room 52.321)

Abstract
We present a method of rhythm transcription (i.e., automatic recognition of note values in music performance signals) based on a Bayesian music language model that describes the repetitive structure of musical notes. Conventionally, music language models for music transcription are trained with a dataset of musical pieces. Because typical musical pieces have repetitions consisting of a limited number of note patterns, better models fitting individual pieces could be obtained by inducing compact grammars. The main challenges are inducing appropriate grammar for a score that is observed indirectly through a performance and capturing incomplete repetitions, which can be represented as repetitions with modifications. We propose a hierarchical Bayesian model in which the generation of a language model is described with a Dirichlet process and the production of musical notes is described with a hierarchical hidden Markov model (HMM) that incorporates the process of modifying note patterns. We derive an efficient algorithm based on Gibbs sampling for simultaneously inferring from a performance signal the score and the individual language model behind it. Evaluations showed that the proposed model outperformed previously studied HMM-based models.

 

"Real-time audio-to-score following and its applications" by Dr. Shinji Sako (and his students). Nagoya Institute of Technology, Japan. (15th Nov, 17:45 h. Room 52.321)

Abstract
We present a robust on-line algorithm for real-time audio-to-score following based on a delayed decision and anticipation framework. We employ Segmental Conditional Random Fields and Linear Dynamical System to model musical performance by human. The combination of these models allows an efficient iterative decoding of score position and tempo. The combined advantages of our approach are the delayed-decision
Viterbi algorithm which utilizes future information to determine past score position with high reliability, thus improving alignment accuracy, and the fact that the future position can be anticipated using an adaptively estimated tempo. We also talk about interim progress of the research and some applications by using this
technique.
