ELLIS Unconference 2023 in Paris

2nd Ellis Unconference, on the HEC campus in Paris, Hawai in Paris, July 23-28 .

This year ICML is in Hawaii. You may not have been lucky enough to have enough funds to go, or you may simply have a few qualms about flying 20,000 km for a mere 4.2 tonnes of CO2. Nevertheless, you regret not being able to present your work, to find the atmosphere of a conference, with people working on subjects close to yours and with whom you could have productive discussions. Here’s your chance to attend

The concept of the “unconference” diverges substantially from that of the conventional conference. This innovative paradigm involves assembling at a secluded campus to collaborate and exchange intellectual insights.

Our program incorporates the organization of themed workshops that stimulate in-depth exploration of particular areas of interest. Furthermore, we have arranged dedicated workspaces for individuals or small groups eager to delve profoundly into their chosen subjects.

As night falls, we will provide opportunities to connect live to ICML tutorials, thus, enhancing knowledge acquisition and exposure to experts in the field. Additionally, we intend to host insightful discussions, encouraging the participants to share their perspectives, debate on relevant issues, and contribute to collective wisdom.

Coming to the unconference

The event will take place on the HEC campus near Paris at the following address: 1 Rue de la Libération, 78350 Jouy-en-Josas.
