ABRA: An algorithm which cannot converge to low-quality Nash equilibria
Vartika Singh, Philip N. Brown
We consider a game theoretic approach to solve multi-agent coordination problems with submodular objectives. It is known for such problems that the Nash equilibria for the correspo…
Structural MRI Synthesis for Alzheimer's Disease via Conditional Diffusion on Anatomical Masks
Muge Zhang, Muhammad Ali Khaliq, Jamal Alsakran +2
Recent advances in generative machine learning models have significantly improved medical imaging, offering promising solutions for data augmentation, privacy preservation, and imp…
Performance Analysis and Optimization of 3D Generative Diffusion Models across GPU Architectures
Jeeho Ryoo, Yongchan Jung, Muhammad Ali Khaliq +3
Diffusion models have become essential for high-fidelity 3D MRI synthesis, yet their deployment remains constrained by substantial GPU resource demands arising from hundreds of U-N…
Chiral solitary waves in a nonlinear topological insulator model
Troy I. Johnson, Justin T. Cole
An outstanding challenge in the field of topological insulators is the realization of nonlinear systems that support coherent traveling waves. Highly nonlinear lattices can suffer…
Explainable AI: Context-Aware Layer-Wise Integrated Gradients for Explaining Transformer Models
Melkamu Abay Mersha, Jugal Kalita
Transformer models achieve state-of-the-art performance across domains and tasks, yet their deeply layered representations make their predictions difficult to interpret. Existing e…
Toxicity in Online Platforms and AI Systems: A Survey of Needs, Challenges, Mitigations, and Future Directions
Smita Khapre, Melkamu Abay Mersha, Hassan Shakil +2
The evolution of digital communication systems and the designs of online platforms have inadvertently facilitated the subconscious propagation of toxic behavior. Giving rise to rea…
