SAYAS NUMERICS DAY 5/03/2025 (formerly Delmar Numerics Day) - Annual Workshop on Computational Mathematics

This is an annual meeting on research in computational mathematics in Maryland, DC, Delaware, Virginia and vicinity organized by

Sayas Numerics Day is named in honor of Francisco Javier Sayas (1968-2019). In addition to his many other achievements, he played a key role in establishing and running DelMar Numerics Day, and was dedicated to its mission of giving especially younger mathematicians an opportunity to share their work.

SAYAS NUMERICS DAY 2025 will take place as an IN-PERSON ONLY MEETING

on Saturday, May 3, 2025, 9:30am-5:50pm
Location: University of Delaware
Keynote talk: Ilse Ipsen (NC State)
An Introduction to Randomized Matrix Computations

We present a 'user-friendly' introduction to randomized matrix algorithms, with several case studies that focus on the ideas and intuition behind randomization.
The concerted development of randomized matrix algorithms started in the theoretical Computer Science community in the nineteen-nineties. At first a purely theoretical enterprise, these algorithms have become practical to the point that they are being used by domain scientists; and general purpose software libraries, such as RandBLAS and RandLAPACK, are under development.
Many randomized matrix algorithms reduce the problem dimension by replacing the original matrix with a lower-dimensional 'sketch'. We illustrate this on the basic problem of matrix multiplication, and on the solution of least squares/regression problems. Along the way, we discuss sampling modalities (data-aware, oblivious), developments in high-dimensional probability (matrix concentration inequalities, matrix coherence), numerical issues (problem conditioning), and the analysis of the error due to randomization.
There will be about 12 contributed talks (20 minutes each, including questions), selected by the scientific committee.
The deadline for submitting talks is MARCH 28, 2025
We particularly encourage graduate students and early career researchers to attend and submit talks.
