Stochastic full waveform inversion with deep generative prior for uncertainty quantification
Yuke Xie, Hervé Chauris, Nicolas Desassis
To obtain high-resolution images of subsurface structures from seismic data, seismic imaging techniques such as Full Waveform Inversion (FWI) serve as crucial tools. However, FWI i…

A Generalized Convolution Model and Estimation for Non-stationary Random Functions
Francky Fouedjio, Nicolas Desassis, Jacques Rivoirard
Standard geostatistical models assume second order stationarity of the underlying Random Function. In some instances, there is little reason to expect the spatial dependence struct…

Estimation of Space Deformation Model for Non-stationary Random Functions
Francky Fouedjio, Nicolas Desassis, Thomas Romary
Stationary Random Functions have been successfully applied in geostatistical applications for decades. In some instances, the assumption of a homogeneous spatial dependence structu…
