GEOSTAT is an INRIA project located at INRIA Bordeaux Sud-Ouest (INRIA BSO), inside the theme: applied mathematical computation and simulation, optimization, learning and statistical methods.

The team specializes in the analysis of complex and natural signals using ideas and methods from statistical physics:  evidencing subtle statistical processes in signal data [example: statistical properties associated to multifractal spectra or turbulence], then challenge/modify the theoretical models to explain the observed geometric/statistical properties from  modeling of the dynamics.

Keywords: signal processing, sparse representations, compact representations, universality classes, wavelets, turbulence, super-resolution, physical models, statistical physics.

Main thematics:

• signals from universe data [astrophysics, earth observation],
  
• biophysiological signals [heart, speech].

Applied/transfer thematic:

• sparsity and non-convex optimization [Labcom with i2S company].
