Web-Integrated Deepfake Detection of Manipulated Political Audio Using CNN and Wav2Vec2 Transformer Models

Deepfake audio poses increasing risks to political forensics by enabling scalable misinformation, speaker impersonation, and identity spoofing. In response to this challenge, this paper presents a web-integrated deepfake detection framework for manipulated political speech together with a politically grounded multiling...

A Multi-Agent Reinforcement Learning Congestion Control Protocol for Wireless Networks

Multi-hop wireless ad-hoc networks (WANETs) are expected to expand significantly over the next years. The limited resources characterizing many WANET deployments, make necessary the efficient use of resources. One common practice to improve efficiency is congestion control. The highly dynamic settings and the need for...
