Computer Science/Discrete Mathematics Seminar I

Towards a theory of non-commutative optimization: geodesic 1st and 2nd order methods for moment maps and polytopes
Rafael Oliveira
10:30am | Simonyi Hall 101
Scaling problems, such as operator scaling and tensor scaling, have recently found several applications in diverse areas of math and CS. They have been used to give efficient...

Institute for Advanced Study/Princeton University Joint Astrophysics Colloquium

Red Supergiants: New Perspectives on Dying Stars
Emily Levesque
11:00am | Bloomberg Hall Lecture Hall
Red supergiants (RSGs) are the helium-fusing descendants of moderately massive (10-25Mo) stars. As the coldest and largest (in physical size) members of the massive star...

Cosmic Ray Transport and the Galaxy Gas Cycle
Chad Bustard
11:00am | Peyton Hall, Dome Room, Room 201
Despite representing only a billionth of the gas population, cosmic rays have enough energy to significantly shape the structure of the ISM, the supernova-driven outflows that...

Seminar on Theoretical Machine Learning

Optimization Landscape and Two-Layer Neural Networks
Rong Ge
12:00pm | Dilworth Room
Modern machine learning often optimizes a nonconvex objective using simple algorithm such as gradient descent. One way of explaining the success of such simple algorithms is...

Galactic Archeology of the Brightest Cluster Galaxy M87
Alexa Villaume
12:15pm | Peyton Hall, Room 033 (basement)
The galactocentric radial metallicity gradients of GC systems can be used to probe the assembly histories of galaxies but doing so is complicated by: 1.) a GC system is an...
