Multilevel neural networks with dual-stage feature fusion for human activity recognition
Abeer FathAllah Brery, Ascensión Gallardo-AntolÃn, Israel Gonzalez-Carrasco +1
Human activity recognition (HAR) refers to the process of identifying human actions and activities using data collected from sensors. Neural networks, such as convolutional neural…
Comparison of window shapes and lengths in short-time feature extraction for classification of heart sound signals
Mahmoud Fakhry, Abeer FathAllah Brery
Heart sound signals, phonocardiography (PCG) signals, allow for the automatic diagnosis of potential cardiovascular pathology. Such classification task can be tackled using the bid…
Elastic Net Regularization and Gabor Dictionary for Classification of Heart Sound Signals using Deep Learning
Mahmoud Fakhry, Ascensión Gallardo-AntolÃn
In this article, we propose the optimization of the resolution of time-frequency atoms and the regularization of fitting models to obtain better representations of heart sound sign…
Audio Source Separation in Reverberant Environments using -divergence based Nonnegative Factorization
Mahmoud Fakhry, Piergiorgio Svaizer, Maurizio Omologo
In Gaussian model-based multichannel audio source separation, the likelihood of observed mixtures of source signals is parametrized by source spectral variances and by associated s…
