Artificial intelligence, mathematics and physics

27-28 September, 2021

CY Advanced Studies, Maison Internationale de la Recherche, CY Université Cergy-Paris

Organisers: A. Honecker (CY Cergy-Paris), R.A. Römer (Warwick)


Background and Purpose

Artificial intelligence and its incarnation as machine learning have matured to the level that researchers in fields such as Condensed Matter theory have during the past few years started to use the related tools in their ow research activities. First applications include the characterization of physical properties, such as identification of phases, as well as the determination of model parameters. In mathematics, there are questions about the framework behind machine learning and the characterization of the output of artificial intelligence. Further far-reaching consequences include ethical questions about the way how research is performed, and in particular ethical issues once human beings become a subject of such data-driven research themselves.

The purpose of this 2-day workshop is to bring together a broad panel of researchers from CY Cergy Paris Université with active interest in such questions, their international partners, notably from the University of Warwick and the MajuLab in Singapore, and a selection of both regional and international experts in the field in order to review the current status and to explore both scientific perspectives as well as potential future projects for collaboration.

Participation is by invitation only. Please contact an organizer if you think this workshop looks as if it would be of interest to you. Normally, we would be happy to accept self-invitations, but may not be able to pay for any expenses in this case.

The symposium will start at 09:00 - 10:00 a.m. on Monday, September 27th, 2021, at CY Advanced Studies. Note that CY Advanced Studies is located at the outskirts of Neuville and not in Cergy centre. See for travel details and for maps. In case you come by car, parking is available for delegates at our car park.This list of participants is accurate as of 26/09/21.

Venue and Accommodation

Registration will be held in the entrance hall of CY Advanced Studies. If one travels via CDG airport, then bus 9518 takes you to Cergy Prefecture within 50 minutes. This is much faster than going through Paris centre via Metro and, since the start is at CDG while the end is at Cergy Prefecture, one gets a seat and can "rest" until the end. A PDF download of the schedule is available via here (click on the "telecharger" button for a PDF). The bus starts at stop G of the Roissypole gare bus station at terminal 3 of CDG, easily connected from termials 2 (Air France) and 1 via the airport shuttle CDGVL. The ticket is 2EUR and drivers accept coins and cash (since Covid19, drivers may refuse anything but the correct change!). The last leg from Cergy prefecture (train station) is a single stop towards Paris on the RER trains towards "Neuville-Universite". The final 500 meters on foot can be seen here where also travel for car, train and RER from Paris is explained. Car parking will be limited to 2-3 spaces.

The workshop will start with the registration at CY Advanced Studies. Accommodation for invited speakers shall be provided. In case you are self-invited, please arrange your stay privately.
