SONAR: Spectral-Contrastive Audio Residuals for Generalizable Deepfake Detection
Ido Nitzan Hidekel, Ido Nitzan HIdekel, Gal lifshitz +2
Deepfake (DF) audio detectors still struggle to generalize to out of distribution inputs. A central reason is spectral bias, the tendency of neural networks to learn low-frequency…

Training a Distributed Acoustic Sensing Traffic Monitoring Network With Video Inputs
Khen Cohen, Liav Hen, Ariel Lellouch
Distributed Acoustic Sensing (DAS) has emerged as a promising tool for real-time traffic monitoring in densely populated areas. In this paper, we present a novel concept that integ…
