چکیده

Variational data assimilation is a very common method for the initialisation of numerical models. It is widely used for instance in Numerical Weather Prediction systems (Météo-France, UK MetOffice, . . .). It aims at finding an optimal initial solution that will bring the model trajectory closer to observations of the system over a given time window. This is done using optimal control techniques where a cost function depending on the sought initial condition is minimised using an iterative method.

Medical Image Retrieval Based On the Parallelization of the Cluster Sampling Algorithm

Cluster sampling algorithm is a scheme for sequential data assimilation developed to handle general non-Gaussian and nonlinear settings. The algorithm relaxes the Gaussian prior assumption widely used in the data assimilation context to approximate the prior distribution obtained by integrating the posterior distribution in previous assimilation cycles. The algorithm can be in general used to s...

Parallel filter algorithms for data assimilation in oceanography

A consistent systematic comparison of filter algorithms based on the Kalman filter and intended for data assimilation with high-dimensional nonlinear numerical models is presented. Considered are the Ensemble Kalman Filter (EnKF), the Singular Evolutive Extended Kalman (SEEK) filter, and the Singular Evolutive Interpolated (SEIK) filter. Within the two parts of this thesis, the filter algorithm...
