Talk | “Interactive Music Analysis using the DFT and Pitch-Class Distributions extracted from MIDI files” by Fabian C. Moss

Posted on

Fabien C. Moss is a Research Fellow in Cultural Analytics at University of Amsterdam (UvA). Working with large symbolic datasets of musical scores and harmonic annotations, he is primarily interested in Computational Music Analysis, Music Theory, Music Cognition, and their mutual relationship. His research is inherently interdisciplinary and aims to bridge the humanities and the sciences by drawing on methods and concepts from the Musicology and Music Theory, Mathematics, Music Information Retrieval, Data Science and Machine Learning, Music Psychology and Cognition, and the Digital Humanities.

Join us on the 4th of April, at 14:30, in room B015 of FEUP, for the presentation of “Interactive Music Analysis using the DFT and Pitch-Class Distributions extracted from MIDI files”

By the author:

“The discrete Fourier transform (DFT) is a cornerstone of digital signal processing and commonly used to extract periodicities in time-continuous signals.

In recent years, however, mathematical music theorists have begun to explore DFT’s potential when applied not to the time but to the pitch-class domain, where the periodicities are given by equal divisions of the octave [1-3]. Earlier this year, we introduced wavescapes [4], a visualization method of hierarchical pitch-class relations in pieces of music.

Building on this work, we are currently developing midiVERTO [5], an interactive web app to analyze MIDI files using the DFT, that allows users to create wavescapes and inspect the dynamics of pitch-class distributions at several hierarchical levels. In my presentation, I will briefly introduce the underlying theoretical work followed by a tutorial on how to use the app for music analysis.

CreativityTalks | Prof. António Sampaio da Nóvoa will be our next guest

Posted on

There are many “futurisms” that suggest an education without schools, based on the immense possibilities of technologies and artificial intelligence. These “futurisms” gained strength with the pandemic and the different forms of isolation to which we have been subjected. But education does not take place in “confinement”, it always requires a relationship, an encounter, working together. This is not the time to announce the “death of school”, but rather to invent it anew.

“Inventing the School anew” will be the topic of the 6th Creativity Talk, presented by Professor *António Sampaio da Nóvoa, on March 17, at 18:00, at the FEUP’s Anfiteatro Nobre (B032).

The session will be moderated by Amélia Lopes, Full Professor and President of the Scientific Council of the Faculty of Psychology and Education Sciences of the University of Porto.

The participation in the lecture requires a (free) registration at Eventbrite (places available to the capacity of the room by order of registration).

*Bio

António Sampaio da Nóvoa is a Full Professor at the University of Lisbon. He holds a PhD in History from the University of Paris IV-Sorbonne and a PhD in Education Sciences from the University of Geneva. He was Rector of the University of Lisbon between 2006 and 2013. He was Portugal’s Ambassador to UNESCO between 2018 and 2021.

1984 Revisited: Was George Orwell an optimist?

Posted on

Debating privacy in the digital era – 03/02, 14:30, online

George Orwell’s masterpiece “1984” offers today an almost realistic description of the vast surveillance system on which capitalist democracies are now based. For the first time in the history of humanity, electronics have made it possible to bring together in the same instruments and the same gestures the work and the supervision exercised over the worker. Big Brother is no longer a figure of speech – he has become an everyday vulgarity.

This work will serve as inspiration for the Workshop promoted by the Doctoral Program in Digital Media at U.Porto, to be held online on February 3rd, at 14:30.

The afternoon will be dedicated to the theme of privacy in the digital era and intends to address its multiple implications today and to foresee future ones – namely regarding the transparency/opacity of digital systems and its relation with digital literacy, surveillance capitalism, prediction algorithms, among others.

To help this reflection, the session will open with a lecture by Professor Luís Borges Gouveia (Fernando Pessoa University/CITCEM – Transdisciplinary Research Centre “Culture, Space and Memory”), followed by a round table with Amílcar Correia (Co Director of Público newspaper), Arlindo Oliveira (President of INESC) and Filipe Vilas Boas (Artist).

Dealing with memory latency in the age of big data

“Lecture DEI Series
Date: June 25th
Time: 14:00
Room: Auditório A – INESCTEC
Speaker: Walid A. Najjar
Affiliation: Department of Computer Science & Engineering University of California Riverside
Abstract
For over two decades the gap between processor and memory speeds has been the most daunting challenge in computer architecture. The advent of big data applications has exacerbated the problem. Traditional multi-core architecture mitigate memory latency through the use of massive cache hierarchies that take up over 80% of the chip area and a proportional percentage of the energy budget. However, big data applications exhibit very poor data locality and cannot benefits from large cache hierarchies. Such applications will be fully impacted by memory latency. Hardware multithreaded architectures have the ability to mask memory latency by context switching between ready threads when a memory access is performed. Classical hardware multithreaded architectures, such as barrel processors (e.g. the UltraSparc and the Cray XMT), must maintain a full state for every thread which requires a lot of resources. FPGAs allow us the opportunity to configure custom or semi-custom processing cores for specific applications.
In this talk I will describe the implementation of data processing applications on the latency masking Filament architecture using semi-custom data paths.
