The Blessings of Multiple Causes
David M. Blei
12:00pm|Dilworth Room

Causal inference from observational data is a vital problem, but it comes with strong assumptions. Most methods require that we observe all confounders, variables that affect both the causal variables and the outcome variables. But whether we have...

Computer Science/Discrete Mathematics Seminar II

Approximating CSPs on expanding structures, and applications to codes
10:30am|Simonyi Hall 101

I will discuss some recent results showing that the sum-of-squares SDP hierarchy can be used to find approximately optimal solutions to k-CSPs, provided that the instance satisfies certain expansion properties. These properties can be shown to...

Analysis/Mathematical Physics Seminar

Inverse problems for quantum graphs
Pavel Kurasov
3:30pm|Simonyi Hall 101

To solve the inverse spectral problem for the Schrödinger equation on a metric graph one needs to determine:
• the metric graph;
• the potential in the Schrödinger equation;
• the vertex conditions (connecting the edges together).
The inverse...

Theoretical Machine Learning Seminar

Foundations of Intelligent Systems with (Deep) Function Approximators
Simon Du
12:00pm|Dilworth Room

Function approximators, like deep neural networks, play a crucial role in building machine-learning based intelligent systems. This talk covers three core problems of function approximators: understanding function approximators, designing new...

Mathematical Conversations

Hypocoercivity
George Deligiannidis
6:00pm|Dilworth Room

I will talk about an approach to proving exponential mixing for some kinetic, non-diffusive stochastic processes, that have recently become popular in computational statistics community.

Compositional inductive biases in human function learning
Samuel J. Gershman
12:00pm|Dilworth Room

This talk presents evidence that humans learn complex functions by harnessing compositionality: complex structure is decomposed into simpler building blocks. I formalize this idea in the framework of Bayesian nonparametric regression using a grammar...

Weak solutions to the Navier--Stokes inequality with arbitrary energy profiles
Wojciech Ożański
5:00pm|Simonyi Hall 101

In the talk we will focus on certain constructions of weak solutions to the Navier--Stokes inequality (NSI), \[ u \cdot \left( u_t - \nu \Delta + (u\cdot \nabla ) u+ \nabla p \right) \leq 0\] on $\mathbb R^3$. Such vector fields satisfy both the...
