The Conference on Neural Information Processing Systems (abbreviated as NeurIPS) will see a mirror version in Paris this Fall, albeit in advance of the main meeting (which starts the week after on 29 November and in New Orleans, hence with a France connection!). The concept is original in that (interested) authors of accepted 2022 NeurIPS papers will present their paper on 23-24 November. Registration is free. But attendance is not guaranteed if the number of registrations exceed the site capacity, in which case attendees will be selected at random.
