Journée Georges de Rham

The Journée Georges de Rham has been introduced in 1991 by the Troisième Cycle Romand de mathématiques. Since then, it is organized each year during the Spring semester by the mathematics departments of EPFL and of the University of Geneva, and it features two speakers of international fame. The Journée de Rham aims at presenting current developments in mathematics, as well as at stimulating interactions amongst researchers in mathematics and related fields.

2026 Edition

The 2026 Journée Georges de Rham will take place on Wednesday 03 June 2026 in the Conference Room SV1717 at EPFL, from 15:30 to 17:30 followed by an apéritif.

The speakers will be Prof. Hong Wang and Prof. Emmanuel Candès

Professor Candès will deliver a talk titled “What Statistics and AI Oﬀer Each Other?“, exploring how thinking carefully about AI inputs and outputs yields more powerful, safer AI. By examining several vignettes, we shall answer questions such as: how do we train language models under cost constraints? What happens when we’ve exhausted all available data? If I start a clinical trial using the drug AI thinks is best, will it pan out? How can we ensure high-quality products when AI is used in a larger workflow? That is, how do I know whether AI automated a task correctly? AI powered imputations are beginning to substitute for real data when collection of the latter is difficult, slow, or costly. How then should we leverage machine learning predictions both as a substitute for high-quality data and as a tool for guiding real data collection?

Further details coming soon – stay tuned!
