PICS Colloquium: Learning to Model the World (and Yourself) from Vision with Vincent Sitzmann

Penn Institute for Computational Science 3401 Walnut Street, 5th Floor, Philadelphia

Abstract: In this talk, I will discuss recent publications from my group that attempt at learning models of the world and the effect of the actions of an agent within that world self-supervised, solely via interaction. In particular, I will discuss the potential and challenges of video generative models as a candidate for such a […]

PICS Colloquium: A geometric model for superfluid helium-4 with Michal Pavelka

PICS Large Conference Room – 534 3401 Walnut Street, 5A, Philadelphia

Abstract: Superfluid helium is a peculiar liquid. For instance, it stays liquid even at very low temperatures (below 2K), it flows through narrow capillaries without friction, and temperature gradient makes it move even in the absence of pressure gradient. The usual description of superfluid helium-4 relies on the concept of two fluids, a so called […]

PICS Colloquium: Mean flow and turbulence in unsteady urban canopy flows with Marco Giometto

PICS Large Conference Room – 534 3401 Walnut Street, 5A, Philadelphia

Speaker: Dr. Giometto is an Assistant Professor in the Civil Engineering and Engineering Mechanics department at Columbia University and an Amazon Visiting Academic. He studies both fundamental and applied problems related to fluid dynamics and turbulence, with an emphasis on atmospheric boundary layer processes. He received his Ph.D. in Civil and Environmental Engineering from Braunschweig […]
