### 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...

### 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.

### 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...

### Analysis - Mathematical Physics

Dimerization and N ́eel order in different quantum spin chains through a shared (classical) loop representation
Michael Aizenman
5:00pm | Simonyi 101
The spin-S quantum spin chain, with a projection-based antiferromagnetic interaction, and the antiferromagnetic XXZ spin-1/2 chain exhibit different forms of translation...

### Computer Science/Discrete Mathematics Seminar I

An Improved Cutting Plane Method for Convex Optimization, Convex-Concave Games and its Applications
Zhao Song
11:00am | Simonyi Hall 101
Given a separation oracle for a convex set $K \subset \mathbb{R}^n$ that is contained in a box of radius $R$, the goal is to either compute a point in $K$ or prove that $K$...
