Title: Mathematical Foundations for Engineering AI Systems

Speaker: Robert Nowak
Date and Time: 09/27/2023 4:15PM ET
Location: Phillips 233 and Zoom

Abstract: This talk delves into the evolution and understanding of AI systems through the lens of mathematical functions. The genesis of modern AI systems is rooted deeply in years of trial and error, which have led to cutting-edge deep learning architectures. In recent years, novel mathematical frameworks have emerged to dissect these systems further, enhancing our understanding of their fundamental workings. With a focus on our recent work on ‘Radon-Domain Bounded Variation Spaces’, the talk illuminates how these innovative function spaces unravel key elements contributing to the current success of AI systems. Further, the talk explores how these discoveries pave the path for a rigorous understanding and improvement of AI. Ultimately, the aim is to harness these insights and theories to engineer AI systems mirroring the robustness, reliability, and interpretability of contemporary communication systems. This talk is based on joint work with Rahul Parhi, Joe Shenouda, and Liu Yang.
