(26/10/2022) Matt Thorpe: A Random Walk from Semi Supervised Learning to Neural Networks

Abstract: Semi-supervised learning is the problem of finding missing labels; more precisely one has a data set of feature vectors of which a (often small) subset are labelled. The semi-supervised…

(19/10/2022) Antonio Vergari: Semantic Probabilistic Layers for Neuro-Symbolic Learning

Abstract: Many structured-output prediction (SOP) tasks in machine learning sport both soft (probabilistic) and hard (symbolic) constraints. Extending current deep learning architectures to correctly…

(14/10/2022) Mattia Sensi: Delayed loss of stability in multiple time scale models of natural phenomena

Abstract: Numerous real-world phenomena exhibit mechanisms evolving on greatly different time scales. In this talk, we focus on delayed loss of stability in two classes of mathematical models, namely…

(05/10/2022) Sid Mishra: Deep Learning and computations of PDEs

Abstract: Partial Differential Equations (PDEs) are ubiquitous in the sciences and engineering. Although very successful, traditional numerical methods can be very expensive, even infeasible, for a…

(28/09/2022) Francisco Bernal: Taming Amdahl's "curse" with probabilistic domain decomposition

Abstract: To solve a large-scale boundary value problem on a supercomputer, the problem domain is partitioned into smaller subdomains that can be tackled by individual processors. Since those…
