[Statlist] Afonso Bandeira: MADZ+: Weinan E (Princeton) on ``A Mathematical Perspective of Machine Learning'' this Wednesday

[Maurer Letizia]

Hi all,

I am very happy to announce Weinan E will speak this Wednesday on the newly created MADZ+ (Math and Data Zurich) seminar, over Zoom. I have heard this particular talk be mentioned a few times, and am particularly excited to finally get to see it. Highly recommend it to everyone.

Seminar: MADZ+
Date: Wednesday, April 1st
Time: 16:00 Zurich time
Place: Seminar will take place through Zoom, invitation is below.
Speaker: Weinan E (Princeton): https://web.math.princeton.edu/~weinan/
Title: A Mathematical Perspective of Machine Learning
Abstract: The heart of modern machine learning is the approximation of high dimensional functions.
Traditional approaches, such as approximation by piecewise polynomials, wavelets, or
other linear combinations of fixed basis functions, suffer from the curse of
dimensionality. We will discuss representations and approximations that overcome
this difficulty, as well as gradient flows that can be used
to find the optimal approximation. We will see that at the continuous level, machine
learning can be formulated as a series of reasonably nice variational and PDE-like problems.
Modern machine learning models/algorithms, such as the random feature and shallow/deep
neural network models, can be viewed as special discretizations of such continuous problems.
At the theoretical level, we will present a framework that is suited for analyzing
machine learning models and algorithms in high dimension, and present results that
are free of the curse of dimensionality.
Finally, we will discuss the fundamental reasons that are responsible for the success of
modern machine learning, as well as the subtleties and mysteries that still remain to be
understood.

IMPORTANT: Some of the talks will be recorded and made public afterwards (provided the speaker is happy with that). While we plan to remove the Questions&Answers part after the talk from the recording, you should know that if you ask a question during the actual talk it might show up in the recording; if something is not clear and you want to ask a question while the speaker is presenting but don't want to show up in the recording write on chat and I can ask it; I'll try to pay attention to the chat while I host (if you don't mind showing on the recording you can interrupt the speaker normally, I'll moderate if needed).

Best,
Afonso
