Investigating the Potential of Multi-Stage Score Fusion in Spoofing-Aware Speaker Verification

Oguzhan Kurnaz, Tomi Kinnunen, Cemal Hanilci · 2025

Despite improvements in automatic speaker verification (ASV), vulnerability against spoofing attacks remains a major concern. In this study, we investigate the integration of ASV and countermeasure (C…

Planning Random path distributions for ambush games in unstructured environments

Emmanuel Boidot, Eric Feron · 2012

Operating vehicles in adversarial environments require non-conventional planning techniques. A two-player, zero-sum non-cooperative game is introduced, which is solved via a linear program. An extensi…
