Dimensionality Reduction for Hyperspectral Image Classification
Mohamed Cherifi, Ammar Mesloub, Mohammed Nabil El Korso +2
This paper addresses the issue of supervised classification in the context of hyperspectral satellite images. It deals with two fundamental aspects: dimensionality reduction of dat…
Robust Expectation-Maximization for Covariance Estimation in SIRV Models with Missing Data: Application to InSAR Time Series
M. Cherifi, M. N. El Korso, A. Hippert-Ferrer +1
This paper presents a robust Expectation-Maximization framework for covariance estimation in Scale-Invariant Random Vector (SIRV) models with missing data under ignorable missingne…
Multifrequency Array Calibration in Presence of Radio Frequency Interferences
Yassine Mhiri, Mohammed Nabil El Korso, Arnaud Breloy +1
Radio interferometers are phased arrays producing high-resolution images from the covariance matrix of measurements. Calibration of such instruments is necessary and is a critical…
Robust low-rank covariance matrix estimation with a general pattern of missing values
Alexandre Hippert-Ferrer, Mohammed Nabil El Korso, Arnaud Breloy +1
This paper tackles the problem of robust covariance matrix estimation when the data is incomplete. Classical statistical estimation methodologies are usually built upon the Gaussia…
Robust Calibration of Radio Interferometers in Non-Gaussian Environment
Virginie Ollier, Mohammed Nabil El Korso, Rémy Boyer +2
The development of new phased array systems in radio astronomy, as the low frequency array (LOFAR) and the square kilometre array (SKA), formed of a large number of small and flexi…
A Bayesian Lower Bound for Parameter Estimation of Poisson Data Including Multiple Changes (extended)
Lucien Bacharach, Mohammed Nabil El Korso, Alexandre Renaux +1
This paper derives lower bounds for the mean square errors of parameter estimators in the case of Poisson distributed data subjected to multiple abrupt changes. Since both change l…
