Statistics Seminar Series: Scalable Bayesian optimization for high dimensional expensive functions

Matthias Poloczek

Abstract: Bayesian optimization has recently emerged as a powerful method for the sample-efficient optimization of expensive black-box functions. These functions do not have a closed-form and are evaluated for example by running a complex simulation, a lab experiment, or solving a PDE. Use cases... Read More

AM Seminar: Cosmic Ray Feedback in Galaxies

Peng Oh

Abstract Cosmic Rays are energetic relativistic particles which are accelerated at shocks. They permeate our Galaxy and have a comparable energy density to the thermal gas. Even though they propagate at the speed of light, they are confined for much longer than the light crossing time, by... Read More

AM Seminar: Toward Large-scale Assimilative Models of Solar Magnetic Activity

William Abbett
Research Physicist and Senior Fellow

Abstract How magnetic energy and flux emerges from the turbulent convective interior of the Sun into the solar atmosphere is of great importance to a number of challenging problems in solar and heliospheric physics. With the wealth of data from space and ground-based observatories, it is evident... Read More
