String-Math Seminar: Integrability of higher genus refined Chern-Simons theory

Seminar | May 8 | 2-3 p.m. | 402 LeConte Hall

 Shamil Shakirov, Harvard University

 Department of Mathematics

It is known that Chern-Simons topological quantum field theory admits a one-parameter deformation – refinement – in the genus 1 sector. I will tell about a genus 2 generalization of this fact. Just like in the torus case, the crucial role is played by an interesting quantum-mechanical integrable system, which is a genus 2 generalization of Ruijsenaars-Schneider-Macdonald system. The knowledge...   More >

Low-dimensional Structures and Deep Models for High-dimensional (Visual) Data

Seminar | May 8 | 2-3 p.m. | Soda Hall, Wozniak Lounge (430)

 Yi Ma, Professor and Executive Dean, School of Information Science and Technology, ShanghaiTech University

 Electrical Engineering and Computer Sciences (EECS)

In this talk, we will discuss a class of models and techniques that can effectively model and extract rich low-dimensional structures in high-dimensional data such as images and videos, despite nonlinear transformation, gross corruption, or severely compressed measurements.

Dissertation Talk: Learning from People

Seminar | May 8 | 4-5 p.m. | 400 Cory Hall

 Nihar Bhadresh Shah, EECS, UC Berkeley

 Electrical Engineering and Computer Sciences (EECS)

Learning from people represents a new and expanding frontier for data science. Two critical challenges in this domain are of developing algorithms for robust learning and designing incentive mechanisms for eliciting high-quality data. In this talk, I describe progress on these challenges in the context of two canonical settings, namely those of ranking and classification. In addressing the first...   More >

Spatial release from masking and the precedence effect in asymmetric hearing loss: Berkeley Ear Club

Colloquium | May 8 | 4 p.m. | Tolman Hall, Beach Room 3105

 Richard Freyman, Communication Disorders U Mass. Amhearst

 Department of Psychology

Analysis and PDE Seminar: Strong cosmic censorship in spherical symmetry for two-ended asymptotically flat initial data

Seminar | May 8 | 4:10-5 p.m. | 740 Evans Hall

 Sung-Jin Oh, KIAS

 Department of Mathematics

Black holes are perhaps the most celebrated predictions of general relativity. Miraculously, stationary black hole spacetimes arise as explicit (i.e., exact expression can be written down!) solutions to the (vacuum) Einstein equation. Looking at these explicit solutions leads to an intriguing observation: While the black hole exterior looks qualitatively similar, the structure of the interior, in...   More >
