Title: Training Neural Networks: The Bigger the Better?
Speaker: Ohad Shamir - COLLOQUIUM LECTURE http://www.wisdom.weizmann.ac.il/~shamiro/
Affiliation: Weizmann Institute
Host: Yuval Filmus

Abstract:


Artificial neural networks are nowadays routinely trained to solve challenging learning
tasks, but our theoretical understanding of this phenomenon remains quite limited. One
increasingly popular approach, which is aligned with practice, is to study how making the
network sufficiently large (a.k.a. ''over-parameterized'') makes the associated training
problem easier. In this talk, I'll describe some of the possibilities and challenges in
understanding neural networks using this approach.

Based on joint works with Itay Safran and Gilad Yehudai.


Short Bio:
============
Ohad Shamir is a faculty member at the Department of Computer Science 
and Applied Mathematics at the Weizmann Institute. He received his PhD 
in 2010 at the Hebrew University, and between 2010-2013 and 2017-2018 
was a researcher at Microsoft Research in Boston. His research focuses 
on theoretical machine learning, in areas such as theory of deep 
learning, learning with information and communication constraints, and 
topics at the intersection of machine learning and optimization. He 
received several awards, and served as program co-chair of COLT as well 
as a member of its steering committee.
