## APPM Department Colloquium - Michael D. Schneider

Sept. 18, 2020

Michael D. Schneider, Group Leader for Astronomy & Astrophysics Analytics, Physics Division, Lawrence Livermore National Laboratory Quantum Machine Learning using Gaussian Processes Quantum computers may be transformative for a variety of computational tasks. We are pursuing machine learning methods for near-term quantum devices that may show advantage over classical computers...

## Complex/Dynamical Systems Seminar - Nicholas Landry

Sept. 17, 2020

Nicholas Landry, Department of Applied Mathematics, University of Colorado Boulder The effect of heterogeneity on hypergraph contagion models The dynamics of network social contagion processes such as opinion formation and epidemic spreading are often mediated by interactions between multiple nodes. Previous results have shown that these higher-order interactions can profoundly...

## APPM Department Colloquium - Béatrice M. Rivière

Sept. 4, 2020

Béatrice M. Rivière, Noah Harding Chair and Professor of Computational and Applied Mathematics, Rice University Diffuse Interface Methods for Two-Phase Flows in Digital Rock Modeling multicomponent flows in porous media is important for many applications relevant to energy and environment. Advances in pore-scale imaging, increasing availability of computational resources, and...

## Mathematical Biology Seminar - Sabina Altus

Aug. 31, 2020

Sabina Altus, Department of Applied Mathematics, University of Colorado Boulder Asymptotic Behavior of a Highly-Structured Population as a Semigroup Perturbation Cyanobacteria are photosynthetic microorganisms with promising applications in renewable energy and agriculture as they are able to convert light energy into more stable forms of chemical energy, such as biomass,...

## APPM Department Colloquium - Persi Diaconis

Aug. 28, 2020

Persi Diaconis, Mary V. Sunseri Professor of Statistics and Mathematics, Stanford University ADDING NUMBERS AND SHUFFLING CARDS When numbers are added in the usual way, 'carries' accrue along the way. It is natural to ask 'how do the carries go?' Is there a carry 'about half the time? If there...

## Statistics, Optimization, and Machine Learning Seminar - Pratyush Tiwary (Virtual)

April 28, 2020

Pratyush Tiwary; Department of Chemistry & Biochemistry and Institute for Physical Science and Technology; University of Maryland From atoms to emergent dynamics (with help from statistical physics and artificial intelligence) ABSTRACT: The ability to rapidly learn from high-dimensional data to make reliable predictions about the future of a given system...

## Applied Math Colloquium - Lou Pecora

Feb. 28, 2020

Lou Pecora, Naval Research Laboratory Cluster Synchronization of Chaotic Systems in Complex Networks The concept of synchronized systems has been around for centuries with one of the earliest studies being on the synchronization of clocks by Christiaan Huygens in the mid 1700’s. By the mid 1900’s it was well-known how...

## Stats, Optimization, and Machine Learning Seminar - Anindya De

Feb. 25, 2020

Anindya De, Department of Computer and Information Science, University of Pennsylvania Testing noisy linear functions for sparsity Consider the following basic problem in sparse linear regression -- an algorithm gets labeled samples of the form (x, + \eps) where w is an unknown n-dimensional vector, x is drawn from a...

## Nonlinear Waves Seminar - Vera Hur

Feb. 25, 2020

Vera Hur, Department of Mathematics, University of Illinois Stokes waves in a constant vorticity flow: theory and numerics Stokes in the 1800s made many contributions about periodic waves at the surface of water, under the influence of gravity, propagating in permanent form a long distance at a practically constant velocity...
