Tight Bound for Sum of Heterogeneous Random Variables: Application to Chance Constrained Programming

Autor: Jacquet, Quentin, Zorgati, Riadh

We study a tight Bennett-type concentration inequality for sums of heterogeneous and independent variables, defined as a one-dimensional minimization. We show that this refinement, which outperforms the standard known bounds, remains computationally

Entropic Lower Bound of Cardinality for Sparse Optimization

Autor: Jacquet, Quentin, Bialecki, Agnes, Ghaoui, Laurent, Gaubert, Stéphane, Zorgati, Riadh

We introduce a family of cardinality's lower bounds, defined as ratios of norms. We prove that the tightest bound of the family is obtained as a limit case, and involves a Shannon entropy. We then use this entropic lower bound in sparse optimization

International audience; In the view of optimizing the maintenance cost of combustion turbine, it is necessary to predict remaining blade coating life. This goal can be achieved by using a multi-frequency Eddy Current non-destructive technique for ass
