This paper considers the linear-Gaussian filtering problem in large-dimensions, a framework in which the Kalman filter (KF) can be computationally prohibitive. As a remedy, a hybrid …

We present, in this paper, a new unsupervised method for joint image super-resolution and separation between smooth and point sources. For this purpose, we propose a Bayesian …

In this paper a nonlinear inverse scattering problem is solved by means of a variational Bayesian approach. The objective is to detect breast tumor from measurements of the …
Cette thèse préparée au CEA Léti, Minatec Campus, Grenoble, et à l'IMS, Bordeaux, s' inscrit dans le thème du traitement de l'information pour des données protéomiques. Nous …
In this paper, first the basics of Bayesian inference with a parametric model of the data is presented. Then, the needed extensions are given when dealing with inverse problems and …
