How well are open sourced AI-generated image detection models out-of-the-box: A comprehensive benchmark study
Simiao Ren, Yuchen Zhou, Xingyu Shen +9
As AI-generated images proliferate across digital platforms, reliable detection methods have become critical for combating misinformation and maintaining content authenticity. Whil…
Stochastic Optimization Models for a Home Service Routing and Appointment Scheduling Problem with Random Travel and Service Times
Man Yiu, Tsang, Karmel S. Shehadeh
We study a routing and appointment scheduling problem with uncertain service and travel times arising from home service practice. Specifically, given a set of customers within a se…
Can Multi-modal (reasoning) LLMs work as deepfake detectors?
Simiao Ren, Yao Yao, Kidus Zewde +8
Deepfake detection remains a critical challenge in the era of advanced generative models, particularly as synthetic media becomes more sophisticated. In this study, we explore the…
On the Galois module structure of the square root of the inverse different in abelian extensions
Cindy, Tsang
Let be a number field with ring of integers and a finite group of odd order. If is a weakly ramified -Galois -algebra, then its square root $A_h…
