GuitarSet: A Dataset for Guitar Transcription
Speaker: Diego de Benito Gorrón. Abstract: Based on https://guitarset.weebly.com/uploads/1/2/1/6/121620128/xi_ismir_2018.pdf. The guitar is a popular instrument for a variety of reasons, including its ability to produce polyphonic sound and its musical versatility. The resulting variability of sounds, however, poses significant challenges… Read More
Representing evidence for Bayesian updating: compositional evidence, privacy and calibration
Speaker: Paul-Gauthier Noé. Abstract: Attribute privacy in multimedia technology aims to hide only one or a few personal characteristics, or attributes, of an individual rather than the full identity. To give a few examples, these attributes can be the sex,… Read More
Detection of abnormalities in electrocardiograms with 2 sensors using machine learning
Speaker: Ana Molina Conesa. Abstract: This talk is based on the Physionet Challenge 2021, in which participants aim to design and implement an algorithm capable of automatically identifying any cardiac abnormalities present in electrocardiogram (ECG) recordings with 12, 6, 4,… Read More
