Interdisciplinary seminar

Since January 2022, discover monthly the interdisciplinary research activities of ITI IRMIA++ members.

The sessions will take place on the 3rd Thursday of each month at 9:00 (excepted during university breaks).
You can attend both at IRMA conference room and by visioconference.

 

20/01/2022 - Emmanuel Franck (IRMA)  Learning, geometry and PDEs, a promising interaction?

 9:00

 IRMA Conference Room and visioconference at https://bbb.unistra.fr/b/hum-51d-suf-mzq

Abstract: In this talk, we want to introduce different examples or problems of interaction between deep learning, geometry, PDEs and numerical methods. We will start by illustrating the ability of deep learning to deal with physical problems starting from a classical problem in fluid mechanics: the closure. In a second step, we will introduce recent works mixing learning and differential geometry which allow to tackle unstructured data. We will illustrate this with simple examples from PDEs. Finally, we will show how ideas from analytical mechanics (and symplectic geometry) can interact with machine learning and numerical simulations of PDEs.

About the speaker: Emmanuel Franck did his Ph.D. thesis from 2009 to 2012 at the CEA on the numerical approximation of the radiative transfer equation. After that he did a 2 year post-doc at the Max Planck Institute for Plasma Physics in Munich on numerical methods for MHD in nuclear fusion. He is an INRIA young researcher since 2014 and his work focuses on the numerical approximation of PDEs in fluid mechanics and plasma physics. He is a member of the Modelling and Control (MOCO) research group at IRMA, Strasbourg.
