Musicians make most of their money from live performance these days, but recordings of live concerts can just make you long for the original studio versions. However, there are exceptions. Bruce is one of them. Here is a live version of Hungry Heart. If you want the original for comparison, here it is.

Condition numbers of tensor decompositions
Nick Vannieuwenhoven
(KU Leuven)
Abstract
Tensor decomposition express a tensor as a linear combination of elementary tensors. They have applications in chemometrics, computer science, machine learning, psychometrics, and signal processing. Their uniqueness properties render them suitable for data analysis tasks in which the elementary tensors are the quantities of interest. However, in applications, the idealized mathematical model is corrupted by measurement errors. For a robust interpretation of the data, it is therefore imperative to quantify how sensitive these elementary tensors are to perturbations of the whole tensor. I will give an overview of recent results on the condition number of tensor decompositions, established with my collaborators C. Beltran, P. Breiding, and N. Dewaele.

Oxford Mathematician Arkady Wey has won the Gold Medal for mathematical sciences at the 2023 STEM for BRITAIN poster competition held in the House of Commons on March 6th. Arkady was among 20 researchers presenting their work to dozens of politicians and a panel of expert judges. Oxford Mathematician Oliver Bond was also shortlisted.
