Computer Science/Discrete Mathematics Seminar I

Strong Average-Case Circuit Lower Bounds from Non-trivial Derandomization
Lijie Chen
11:00am | Simonyi Hall 101
We prove that, unconditionally, for all constants a, NQP = NTIME[n^polylog(n)] cannot be (1/2 + 2^(-log^a n) )-approximated by 2^(log^a n)-size ACC^0 circuits. Previously, it...

Members' Seminar

Direct and dual Information Bottleneck frameworks for Deep Learning
Tali Tishby
2:00pm | Simonyi Hall 101
The Information Bottleneck (IB) is an information theoretic framework for optimal representation learning. It stems from the problem of finding minimal sufficient statistics...

Symplectic Dynamics/Geometry Seminar

Classification of n-component links with Khovanov homology of rank 2^n
Boyu Zhang
3:30pm | Simonyi Hall 101
Suppose L is a link with n components and the rank of Kh(L;Z/2) is 2^n, we show that L can be obtained by disjoint unions and connected sums of Hopf links and unknots. This...

Analysis Seminar

"Observable events" and "typical trajectories" in finite and infinite dimensional dynamical systems
Lai-Sang Young
5:00pm | Simonyi Hall 101
Some words in the title are between quotation marks because it is a matter of interpretation. For dynamical systems on finite dimensional spaces, one often equates observable events with positive...

Computer Science/Discrete Mathematics Seminar II

Is the variety of singular tuples of matrices a null cone?
Viswambhara Makam
10:30am | Simonyi Hall 101
The following multi-determinantal algebraic variety plays an important role in algebra and computational complexity theory: SING_{n,m}, consisting of all m-tuples of n x n...

Seminar on Theoretical Machine Learning

Learning from Multiple Biased Sources
Clayton Scott
12:00pm | Dilworth Room
When high-quality labeled training data are unavailable, an alternative is to learn from training sources that are biased in some way. This talk will cover my group’s recent...
Feb 26

Mathematical Conversations

Euler flow with odd symmetry
Hyunju Kwon
6:00pm | Dilworth Room
I’ll introduce the incompressible Euler equations and talk about the solution’s behavior when the vorticity has odd symmetry.
Feb 27

Working Seminar on Nonabelian Hodge Theory

10:00am | Simonyi Hall 101
Feb 27

Seminar on Theoretical Machine Learning

Preference Modeling with Context-Dependent Salient Features
Laura Balzano
12:00pm | Dilworth Room
This talk considers the preference modeling problem and addresses the fact that pairwise comparison data often reflects irrational choice, e.g. intransitivity. Our key...

Joint IAS/Princeton University Number Theory Seminar

A p-adic monodromy theorem for de Rham local systems
Koji Shimizu
4:30pm | Simonyi 101
Every smooth proper algebraic variety over a p-adic field is expected to have semistable model after passing to a finite extension. This conjecture is open in general, but its...
