Publikováno v: Frontiers in Cardiovascular Medicine, Vol 10 (2023)
BackgroundPersistent Atrial Fibrillation (PersAF) electrogram-based ablation is complex, and appropriate identification of atrial substrate is critical. Little is known regarding the value of the Average Complex Interval (ACI) feature for PersAF abla

Unsupervised and Computationally Lightweight Spectrum Sensing in IoT Devices
Autor: Rubén Martín-Clemente, Vicente Zarzoso
Publikováno v: Engineering Proceedings, Vol 27, Iss 1, p 76 (2022)
Principal component analysis (PCA) is a widespread technique in data analysis. Recently, the L1-norm has been proposed as an alternative criterion to classical L2-norm in PCA due to its greater robustness to outliers. The present work shows that, wit

Fibrillatory Wave Amplitude Evolution during Persistent Atrial Fibrillation Ablation: Implications for Atrial Substrate and Fibrillation Complexity Assessment
Autor: Fabien Squara, Didier Scarlatti, Sok-Sithikun Bun, Pamela Moceri, Emile Ferrari, Olivier Meste, Vicente Zarzoso
Publikováno v: Journal of Clinical Medicine; Volume 11; Issue 15; Pages: 4519
Background. Fibrillatory Wave Amplitude (FWA) has been described as a non-invasive marker of atrial fibrillation (AF) complexity, and it predicts catheter ablation outcome. However, the actual determinants of FWA remain incompletely understood. Objec

International audience; The Fukunaga-Koontz transform (FKT) is a powerful supervised feature extraction method used in two-class recognition problems, particularly when the classes have equal mean vectors but different covariance matrices. The presen

Unsupervised Classification of Zero-Mean Data Based on L1-Norm Principal Component Analysis
Autor: Vicente Zarzoso, Susana Hornillo-Mellado, José Luis Camargo, Rubén Martín-Clemente
Publikováno v: Communication and Intelligent Systems ISBN: 9789811610882
This paper shows that L1-norm PCA, a robust variant of principal component analysis (PCA), can distinguish between zero-mean populations by projecting the data onto directions along which the variance is much larger for one population than for the ot

Tensor-Based Noninvasive Atrial Fibrillation Complexity Index For Catheter Ablation
Autor: Walter C. Freitas, Pedro Marinho R. de Oliveira, Lucas de S Abdalah, Vicente Zarzoso
Publikováno v: CinC
Due to the cost-efficiency of the ECG, the interest in noninvasive techniques to assess atrial fibrillation (AF) electrophysiological complexity is increasingly high. Still, ECG-based methods to measure AF complexity are limited in clinical practice
