Le vendredi 28 juin 2019 à 11h00 dans la salle Pierre Cotton du laboratoire, Nguyen Linh Trung de la Vietnam National University, donnera un séminaire intitulé : "Modern subspace tracking for signal processing : A brief review and some developments"
Résumé :
Subspace tracking aims to seek linear low-dimensional structure in a high-dimensional manifold in an adaptive setting. In this aspect, subspace tracking can be considered as a fast implementation of principal component analysis (PCA) for streaming data, which find many applications in signal processing, data analysis, telecommunication, biomedical imaging, and computer vision, etc.
In this talk, we would like to bring up some important aspects of modern subspace tracking for signal processing. First, we review some essential algorithms in the literature (up to 2010) where linear computational complexity of algorithms is the target. Then, we focus on modern subspace tracking which deals with many practical issues (e.g. outliers, missing data, higher-order data structure) and algorithmic issues (e.g. guaranteed convergence analysis). Finally, we will present some developments from our group on this topic, with illustrations in practical applications such as DOA tracking, radio-astronomy, video background-foreground separation, especially EEG signal analysis. Some recent trends and open perspectives are also discussed.
