Asymptotically exact data augmentation: models, properties and algorithms
Maxime Vono, Nicolas Dobigeon, Pierre Chainais
Data augmentation, by the introduction of auxiliary variables, has become an ubiquitous technique to improve convergence properties, simplify the implementation or reduce the compu…
Nonlinear hyperspectral unmixing with robust nonnegative matrix factorization
Cédric Févotte, Nicolas Dobigeon
This paper introduces a robust mixing model to describe hyperspectral data resulting from the mixture of several pure spectral signatures. This new model not only generalizes the c…
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…
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…
