ASCAI MEETING 
Orsay - June 19-20, 2025

- The interface between statistical physics and learning.

- Computational barriers in statistical learning.

 

Organized at Institut de Mathématiques d'Orsay by the franco-german research group ASCAI.

The two days will be structured around two mini-courses and two advanced lectures. They will be preceded by a satellite workshop presenting some recent achievements of the ASCAI group.
