Speaker: Álvaro Sáiz López. Abstract: P300-based brain-computer interfaces (BCIs) provide a non-muscular communication channel for patients with severe motor impairments. This work leverages BigP3BCI, a recently released dataset unifying 18 studies and ~200 subjects, to systematically compare feature extractors for… Read More
Evaluation of P300-Based Brain-Computer Interfaces in Amyotrophic Lateral Sclerosis
Speaker: Julia Reina Boria. Abstract: In this talk, I will present the evaluation of P300-based brain-computer interfaces as an assistive communication technology for people with amyotrophic lateral sclerosis. The work analyzes EEG signals from a P300 dataset and compares different… Read More
Automatic metal subgenre recognition system
Speaker: Alejandro André Vivas Freitas. Abstract: Music can evoke countless emotions regardless of culture or age, and although the classification of musical genres has existed for centuries, automatic classification is a relatively recent discipline (barely two and a half decades… Read More
Audio Event Processing applied to the detection of different frog species.
Speaker: Nicolás Martín Ansorregui. Abstract: Passive Acoustic Monitoring (PAM) in tropical ecosystems faces significant challenges due to overlapping vocalizations and severe class imbalance, often leading to the ‘algorithmic invisibility’ of rare species. This talk presents a deep learning architecture that… Read More
Analysis of Deepfakes and Anti-spoofing in Speaker Verification
Speaker: Alejandro Delgado Montero Abstract: This presentation explores the critical challenge of detecting audio deepfakes and defending speaker verification systems against voice spoofing attacks, evaluated within the frameworks of the ASVspoof 5 and ESDD2 international challenges. We examine the design… Read More
