Lecture 1: March 15th, 2023
Lecture 2: March 22th, 2023

Mathematical Sciences Building, Room 3106, Time: 12 pm

SIAM is hosting a 2-part tutorial session this quarter to help people enter the exciting world of computational mathematics. For this first week, we will walk through the steps at installing python (correctly!) and submitting a project for a Kaggle competition. Please bring your laptops! We will have our representatives there to help with the tutorial, so it will be interactive! The next week, the series continues by exploring computational algebraic geometry and elimination theory. Make sure you have completed the tutorial from the first week in order to fully participate in this live tutorial.

Seminar: Applications of and Challenges Associated With Stochastic Optimization “In the Wild”
Mathematical Sciences Building, Room 1147, 2:10 PM-3:00 PM

Abstract: Due to recent advances in both mathematics and algorithmics, stochastic optimization models are now to the point where they are starting to become computationally tractable at reasonable scales. However, significant challenges remain on both fronts, in terms of both problem classes and application environments that can be addressed. In this talk, I will discuss key applications of stochastic optimization in two large and related application spaces: critical infrastructure protection and power systems operations / planning. The talk will focus on both the applications themselves and mathematical and computational challenges that are inhibiting the broader adoption of stochastic optimization in these contexts.

Abstract: The international Cassini-Huygens spacecraft was launched on October 15, 1997 and had a marathon 7-year 2-billion mile journey to the distant planet Saturn. The 23-foot tall, 14-foot wide, 6-ton spacecraft is the largest most sophisticated outer planet spacecraft ever built, and is in its twelfth year of operation in orbit around the planet Saturn. Cassini-Huygens has been returning extraordinary data about the entire Saturn system: the spectacular rings; the numerous icy satellites with a variety of unique surface features; the giant planet itself; a huge magnetosphere teeming with particles that interact with the rings and moons; and the intriguing moon Titan, which is slightly larger than the planet Mercury, and whose hazy atmosphere is denser than that of Earth. This talk will be an overview of the Cassini-Huygens Mission to Saturn with a summary of the top science returns of its first 12 years in orbit.

Abstract: Exterior ballistics studies the trajectories of bullets and artillery shells, or in Leonard Euler's phrase, the path of an object thrown into the air. Military technologists predicted trajectories using Isaac Newton's model of a point-mass with aerodynamic drag from Euler in 1753 to ENIAC in 1946. For this purpose they invented various computing methods: ballistic tables, numerical integration, differential analyzers, and finally electronic computers. Indeed, the United States supported inventing computers precisely to construct artillery firing tables in the second World War. Beyond the many fascinating historical events, this long period offers a test for understanding the history of engineering technology. I propose a concept of episodic change in the history of engineering analogous to the paradigm shifts in the history of science.

Abstract: The problem of minimizing a vector valued scalar objective function can be approached with a Trust-Region algorithm. This method is based on minimizing Taylor approximations of the objective function subject to a constraint. These constrained problems are the so called Trust-Region subproblems. Our focus is on solving the subproblem when the number of unknowns is large, and the 2nd derivative matrix of the objective function is difficult to compute.

Seminar: Optimization Challenges in Tensor Factorization
Mathematical Sciences Building, Room 2112, 11:00 AM-12:00 PM

Abstract: Tensors are multiway arrays, and tensor decomposition is a powerful tool for compression and data interpretation. In this talk, we demonstrate the utility of tensor decomposition with several examples and explain the optimization challenges, both theoretical and practical. The optimization problems are nonconvex, but they can typically be solved via an alternating approach that yields convex subproblems. We consider open problems such as determining the model complexity, tensor completion, incorporating symmetries and other constraints, handling ambiguities in scaling and permutation, enforcing structure like sparsity, and considering alternative objective functions.

Applied Math Career Talk/Discussion

The first annual Davis SIAM Round-table on Summer Internships, Workshops, and Extra-Academic Experiences was held on October 13th, 2015. At the event several grads discussed a variety of summer opportunities they had pursued. Some of the opportunities included public internships at the NSA and Lawrence Livermore Laboratory, as well as private internships at NASA and Smule, a bay area audio app designer. The event was designed to generate awareness of summer opportunities available outside of academia. To view pictures of the event, check out the Photo Gallery.

Annually, 2008-2013

One of the largest events the SIAM chapter has organized in past years is the Davis SIAM Student Research Conference (DSSRC) which took place in the Spring Quarter at UC Davis. The conferences provided an opportunity for students to promote their research in either a talk or poster session format.
