Two talks will be presented : Alexandre AKSENOV Title. Introduction to strongly b-multiplicative sequences and rarefaction. Abstract. The class of “strongly b-multiplicative sequences” is the class of numerical sequences which are closest to the classical Thue-Morse sequence. This sequence was defined at first as a source of examples of “counter-intuitive…

Hassan Akbari: In this work, we use tensor decomposition methods in application of fetal ECG extraction from abdominal recordings. We propose a linear source separation algorithm based on a measure of quasi-periodicity. The quasi-periodicity is attained through the use of a constraint on both matrix factorization and tensor decomposition problems.…

Saloua Chlaily: Interaction of modalities By using several modalities we aim at enhancing the quality and accuracy of the observed signal. However, the expected improvement is not always obtained. In this talk, we consider a simple model of two modalities and analyze their pertinence and interrelations, in term of mutual…
