  Abstract Advances in AI have revolutionized many domains, yet effectively harnessing 3D data remains a challenge due to the lack of a unified 3D representation across tasks. A recent breakthrough in this area is the 3D Gaussian Splatting primitive, which enables fast and accurate 3D reconstruction from multiple 2D images. However, its limitations in representing sharp, physical objects have prompted us to propose an alternative based on 3D smooth convexes, which demonstrably outperforms traditional approaches in reconstructing fine details. In the realm of medical imaging—where 3D volumetric

  The random matrix theory was started in the 1930s, with notable contributions made by J. Wishart, Baolu Xu and others. During the 1950s of last century, physicist E. Wigner introduced random matrices as a means to simulate the nuclei of heavy atoms, predicting that the spacing between the spectra of heavy atomic nuclei should mirror the spacing between the eigenvalues of random matrices. Many prominent mathematicians also worked on this theory and made very important progress. In this talk, I will begin with some basics on the random matrix theory, then I will discuss some results obtained by my collaborators and myself. Next I will briefly discuss the SYK model, which is now a very active research area in physics. Our objective is to establish a mathematical theory for the SYK model, and I will present some advancements we made as well as some open problems.

  Metrics, Mayhem, and Microservices: Taming the Cloud Observability Beast

  Alessandro Cornacchia, Postdoctoral Fellow

  Cloud applications scale their workload on massively distributed software and hardware infrastructure to deliver swift performance and meet stringent service level objectives. The latest advancements in AI and the promising results delivered by flagship AI models have reinforced this trend, fueling considerable additional investments by all major cloud players to further scale their infrastructure. Yet, fault tolerance and performance debugging remain among the relatively few levers against this exponential growth, demanding ubiquitous system instrumentation and observability to anticipate failures or identify root-causes post-mortem. Overall, observability has become mission-critical to operate cloud technology at scale. In this talk, we introduce the first-ever offloading of observability operations to data centers' Infrastructure Processing Units (IPU) accelerators. This novel architecture can significantly reduce the costs and increase operational efficiency to manage large-scale cloud systems serving millions of users daily.

  An introduction to Virtual Elements in 3D

  Professor Lourenco Beirao da Veiga, University of Milano-Bicocca

  Jan 28, 16:00 - 17:00

  B1, L3, R3119

  The Virtual Element Method (VEM), is a very recent technology introduced in [1] for the discretization of partial differential equations, that has shared a good success in recent years. The VEM can be interpreted as a generalization of the Finite Element Method that allows to use general polygonal and polyhedral meshes, still keeping the same coding complexity and allowing for arbitrary degree of accuracy. The Virtual Element Method makes use of local functions that are not necessarily polynomials and are defined in an implicit way. Nevertheless, by a wise choice of the degrees of freedom and introducing a novel construction of the associated stiffness matrixes, the VEM avoids the explicit integration of such shape functions.
