AI-assisted Tagging of Deepfake Audio Calls using Challenge-Response

arXiv (submitted to SOUPS 2024)

Scammers are aggressively leveraging AI voice-cloning technology for social engineering attacks, a situation significantly worsened by the advent of audio Real-time Deepfakes (RTDFs). RTDFs can clone a target's voice in real-time over phone calls, making these interactions highly interactive and thus far more convincing. Existing literature has largely been ineffective against RTDF threats. We introduce a robust challenge-response-based method to detect deepfake audio calls with high accuracy.

Improving Learnt Local MAPF Policies with Heuristic Search

International Conference on Automated Planning and Scheduling (ICAPS)

We improve a ML local policy by using heuristic search methods on the output probability distribution to resolve deadlocks and enable full horizon planning for Multi Agent Planning (MAPF). We show several model-agnostic ways to use heuristic search with ML that significantly improves the local ML policy's success rate and scalability. To our best knowledge, we demonstrate the first time ML-based MAPF approaches have scaled to similar high congestion as state-of-the-art heuristic search methods.
