An obituary describing Nick's research and leadership contributions will appear in SIAM News in due course. Francoise Tisseur and Des Higham ------------------------------------------------------- From: Jim Uber [log in to unmask] Date: January 18, 2024 Subject: Derivatives of B-Spline Curves with Respect to Values of the Knots Hi All, I've got a problem where I'd like to compute derivatives of the B-Spline S(x) with respect to the knot vector t. I have done this, seemingly successfully, by differentiating the underlying basis functions B_i,k;t(x), starting with its recurrence relationship and deriving the following recurrence relationship for the Jacobian dB/dt. The thing is, I am a little confused (or concerned) that I can't find this sort of thing readily in the literature or existing software. I'd like to know that I'm not missing the boat and should be doing things in a different or better way. If anyone has any sprinkles of advice or pointers for information, I sure would appreciate hearing from you. Thanks, -Jim ------------------------------------------------------- From: Mitchell Graham [log in to unmask] Date: December 21, 2023 Subject: New Book, Rough Volatility Rough Volatility by Christian Bayer, Peter K. Friz, Masaaki Fukasawa, Jim Gatheral, Antoine Jacquier, and Mathieu Rosenbaum Volatility underpins financial markets by encapsulating uncertainty about prices, individual behaviors, and decisions and has traditionally been modeled as a semimartingale, with consequent scaling properties. The mathematical description of the volatility process has been an active topic of research for decades; however, driven by empirical estimates of the scaling behavior of volatility, a new paradigm has emerged, whereby paths of volatility are rougher than those of semimartingales. According to this perspective, volatility behaves essentially as a fractional Brownian motion with a small Hurst parameter. The first book to offer a comprehensive exploration of the subject, Rough Volatility contributes to the understanding and application of rough volatility models by equipping readers with the tools and insights needed to delve into the topic, exploring the motivation for rough volatility modeling, providing a toolbox for computation and practical implementation, and organizing the material to reflect the subject's development and progression. 2023 / xxviii+261/ Softcover / 978-1-61197-777-6 / List $85.00 / SIAM Member $59.50 / FM02 Bookstore link: https://my.siam.org/Store/Product/viewproduct/?ProductId=49881964 ------------------------------------------------------- From: Annalisa Quaini [log in to unmask] Date: January 12, 2024 Subject: Power of Diversity in UQ, Italy, Feb 2024 Are you participating to SIAM UQ24 but find the size and breadth of the conference daunting? ``Power of Diversity in Uncertainty Quantification'' (PoD UQ) is targeted to graduate students and young researchers to ease their approach to SIAM UQ24 and ensure they make the most out of it. PoD UQ will be held the day before the conference starts (i.e., February 26, 2024) and will be hosted by International School for Advanced Studies (Trieste, Italy). The goals PoD UQ are to: i) Introduce students and early-career researchers to the state-of-the-art and current trends in modeling, sampling, and analyzing uncertainties. ii) Offer an excellent chance for networking with both peers and more established researchers. The name of the meeting highlights the central role played by diversity in UQ, a field whose advancement requires the integration of mathematics and statistics, theory and computations. Diversity refers also to the community of under-represent groups that PoD UQ targets for greater inclusivity. The full day event, partially funded by the U.S. National Science Foundation, will have no registration fee. In addition, thanks to the NSF funding, we may be able to provide support towards a one night accommodation for attendees affiliated with U.S. institutions.

During the last years, spectral imagers (e.g., hyperspectral, CT) have become commercially available, which offer in particular great added for quality control in agrofood. However, spectral imaging devices are burdened by the complexity and high dimensionality of generated data compared to classical imagers. In addition, machine learning models typically require large, labelled datasets which are generally unavailable for spectral images. There is thus a need for efficient learning strategies. The objective of this project is to develop tensor-based compression algorithms for efficiently building machine learning models for high- dimensional, spectral images in agrofood applications. In this research work, you will first evaluate the performance of tensor decomposition and compression when applied to spectral data and fed into a machine learning pipeline. Subsequently, you will go well beyond the state of the art and develop novel methods that adapt the tensor decomposition to align better with the machine learning goal (e.g., classification, regression, clustering).
