Physics-Guided Variational Model for Unsupervised Sound Source Tracking
Luan VinÃcius Fiorio, Ivana Nikoloska, Bruno Defraene +3
Sound source tracking is commonly performed using classical array-processing algorithms, while machine-learning approaches typically rely on precise source position labels that are…
Hybrid Real- and Complex-Valued Neural Network Architecture for Speech Enhancement
Luan VinÃcius Fiorio, Luan Vinícius Fiorio, Alex Young +1
This paper investigates hybrid real- and complex-valued neural networks for monaural speech enhancement. While complex-valued models can process time-frequency representations nati…
Hybrid Real- and Complex-valued Neural Network Architecture
Alex Young, Luan VinÃcius Fiorio, Bo Yang +3
We propose a \emph{hybrid} real- and complex-valued \emph{neural network} (HNN) architecture, designed to combine the computational efficiency of real-valued processing with the ab…
Target Speaker Selection for Neural Network Beamforming in Multi-Speaker Scenarios
Luan VinÃcius Fiorio, Bruno Defraene, Johan David +4
We propose a speaker selection mechanism (SSM) for the training of an end-to-end beamforming neural network, based on recent findings that a listener usually looks to the target sp…
