Cyril Laurier defends his PhD thesis on October 19th

Cyril Laurier defends his PhD thesis entitled "Automatic Classification of Musical Mood by Content Based Analysis" on October 19th 2011 at 13:00h in room 55.309 of UPF's Communication Campus.

The members of the jury are:  Petri Toivainen (University of Jyväskylä), Geoffroy Peeters (IRCAM), Emilia Gomez (UPF).

Abstract: Digital music is becoming a major part of the user experience with computers and mobile devices. Automatically organizing this content is a major challenge. In this work, we focus on automatically classifying music by mood. For this purpose, we propose computational models using information extracted from the audio signal. The foundations of such algorithms are based on techniques from the fields of signal processing, machine learning and information retrieval. First, by studying the tagging behavior of a music social network with dimensionality reduction techniques, we find a relevant representation model for mood. We believe that this methodology can be applied to other domains. Then, we propose a method for automatic music mood classification and detail the results for different types of classifiers. We analyze the contributions of audio descriptors and how their values are related to the observed mood, trying to find explanation from psychology and musicology. We also propose a multimodal version of our algorithm using lyrics information, contributing to the field of text retrieval with a new model based on key words differentiating categories. Moreover, after showing the relation between mood and genre, we present a new approach using automatic music genre classification. We demonstrate that genre-based mood classifiers give higher accuracies than standard models. All the proposed algorithms are evaluated with user data. Our audio based approaches, adapted to the context, have been evaluated in international evaluation campaigns. Nevertheless, we propose a rule extraction technique to explicit the strategy behind our models. This method allows to make sense of the classifiers and to understand how they can predict the musical mood.

Seminar by Waldo Nogueira on cochlear implants

On Thursday Oct. 13th 2011 at 15:30h in room 52.321, Waldo Nogueira, postdoc at the MTG, will give a research seminar on "Signal Processing and Sound Perception with Cochlear Implants"

Abstract: Cochlear Implants are implantable medical devices that can restore hearing to people with profound hearing losss. Speech recognition in noise and music perception with these devices are still severely limited. A factor that determines hearing performance with these devices is the signal processing method or strategy implemented in the cochlear implant sound processor. This seminar will present the cochlear implant system and it will review how hearing is perceived with these devices. The most common signal processing methods as well as new techniques to improve pitch perception, music perception and speech intelligibility will presented. The evaluation methods to assess performance with these devices will be also discussed.

Biography: Waldo Nogueira received his Ing. degree (M. Sc.) in Telecommunication Engineering from the Technical University of Catalonia in 2003. He wrote his diploma thesis "Envelope Estimation of Audio Signals based on Predictive Techniques on the Frequency Domain" as an integrated exchange student at the Leibniz University of Hanover. This institution is an active center in multimedia research (audio and video coding and streaming, 3D modeling, face animation, and computer-human interfaces). After completing his Master's Thesis, he worked toward his PhD degree at the Laboratory of Information Technology of the University of Hanover. During his PhD he developed several strategies for cochlear implants, some of which have been commercialized, like the MP3000 by Cochlear Corporation. Furthermore, he did extensive work on designing evaluation methods to assess sound performance using cochlear implants based on auditory nerve models and automatic speech recognizers. This work finished with the publication of his Dissertation: "Design and Evaluation of Signal Processing Strategies for Cochlear Implants based on Psychoacoustic Masking and Current Steering".  In 2008 he joined the European R&D centre of Advanced Bionics in Belgium as a Research Engineer. His main tasks consisted of developing new algorithms for stimulation of cochlear implants and research on electrophysiology of the auditory nerve. In 2009 he became Principal Research Engineer with emphasis in signal processing at the European Centre of the same company in Hanover (Germany). His main tasks consisted of research and development of new audio signal processing algorithms for cochlear implants, electrophysiology and management of research projects with external R&D centres. Since Semptember he is working at the Music Technology Group of the Pompeu Fabra starting a research line on music signal processing and cochlear implants.

Seminar by Bruno Zamborlin on Gesture interaction

On Monday October 10th at 12.00h in room 55.410 Bruno Zamborlin, PhD student in Arts and Computational Technologies, will give a talk on "Gesture interaction design and expressive control of digital media".

ABSTRACT
During the last three years, we studied various methods for computer-based gesture analysis, with the general goal of using body movements to interact with sound and visual media. We realised a system called Gesture Follower that allows for recognition and synchronisation of gestures with digital media.
This research has largely been influenced by sustained collaborations with musicians/composers and dancers/choreographers. I will present the technology and some of these works, including recent collaborations with the composer Lorenzo Pagliei and the violinist Mari Kimura.
Recently, I focused on the usability of these tools. I will present a brand new application called Gesture Interaction Design (GIDE), whose main purpose is to guide the artist in the creation and design of his own gesture vocabulary.
I will also introduce an application of this technology for gesture-driven audio/video mosaicing.

BIO
Bruno Zamborlin is currently doing a joint PhD student in Arts and Computational Technologies between the Goldsmiths Digital Studio, Univ. of London, and the Real-Time Musical Interactions team at IRCAM, Paris.
He previously worked at IRCAM for the last four years focusing in real-time gesture recognition for performing arts.
He studied computer science at the University of Bologna and the Institute of Advanced Computer Science of Leiden and worked for two years at the Centro Tempo Reale in Florence as computer-music software developer.
He collaborated with composers such as Pierre Jodlowsky and Ivan Fedele, and performers such as Mari Kimura and Richard Siegal.
