Joint Bayesian estimation of close subspaces from noisy measurements
Olivier Besson, Nicolas Dobigeon, Jean-Yves Tourneret
In this letter, we consider two sets of observations defined as subspace signals embedded in noise and we wish to analyze the distance between these two subspaces. The latter entai…
On the Fisher information matrix for multivariate elliptically contoured distributions
Olivier Besson, Yuri I. Abramovich
The Slepian-Bangs formula provides a very convenient way to compute the Fisher information matrix (FIM) for Gaussian distributed data. The aim of this letter is to extend it to a l…
Minimum mean square distance estimation of a subspace
Olivier Besson, Nicolas Dobigeon, Jean-Yves Tourneret
We consider the problem of subspace estimation in a Bayesian setting. Since we are operating in the Grassmann manifold, the usual approach which consists of minimizing the mean squ…
