Séminaire de Lucas Brivadis

14h00-15h00 – Online Infinite-dimensional Luenberger observers: application to a crystallization process Lucas Brivadis (LAGEPP, Université Lyon 1) Abstract. During a crystallization process, the Particle Size Distribution (PSD) is a relevant information that needs to be estimated through other measurements, such as the Chord Length Distribution (CLD). The PSD-to-CLD mapping depends on particle geometry. We propose […]

Robust low-rank covariance matrix estimation with missing values and application to classification problems

Speaker — Alexandre Hippert-Ferrer (L2S, CentraleSupelec, Univ. Paris-Saclay) Abstract — Missing values are inherent to real-world data sets. Statistical learning problems often require the estimation of parameters as the mean or the covariance matrix (CM). If the data is incomplete, new estimation methodologies need to be designed depending on the data distribution and the missingness […]
