Sujet :
Data-driven and learning-based strategies for the analysis, modeling and reconstruction of dynamical systems are currently emerging as promising research directions as an alternative to classic model-driven approaches for a wide variety of application fields, including atmosphere and ocean science, remote sensing, computer vision…. [2,3,4]. Especially, deep learning schemes [1] are currently investigated to address inverse problems, i.e. reconstruction of signals or images from observations. Especially, recent works [e.g., 3,4] have shown that one can learn variational models and solvers for the reconstruction.
These internships will specifically investigate the development of deep learning inverse models for the space-time reconstruction of geophysical dynamics from partial observations. We aim to explore and understand how end-to-end neural schemes, such as 4DVarNets [3,5], provide new means to address limitations of operational data assimilation systems, especially for applications to ocean modeling and forecasting using satellite and in situ observations. Both simulated and real case-studies will be of interest.

Keywords: deep learning, inverse problems, data assimilation, space oceanography

Profil du candidat :
