Analysis Seminar

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...

IAS-PNI Seminar on ML and Neuroscience

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...

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...

Seminar on Theoretical Machine Learning

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...

Analysis - Mathematical Physics

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...

Computer Science/Discrete Mathematics Seminar II

Approximating CSPs on expanding structures, and applications to codes
Madhur Tulsiani
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...

Seminar on Theoretical Machine Learning

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...

Mathematical Conversations

What is a Motive?
Pierre Deligne
6:00pm | Dilworth Room
I will explain the source of Grothendieck philosophy of motives, and tell of applications.
