In most stochastic mortality models, either one stochastic intensity process (for example a jump-diffusion process) or a collection of independent processes is used to model the stochastic evolution of survival probabilities. We propose and calibrate a new model that takes inter-age correlations into account. The so-called stochastic logit’s Deltas model is based on the study of the multivariat...

Approche hybride de recommandation des nouvelles collaborations

With the spread of organizations and especially distributed ones, teams are highly dynamic and people are continually seeking for new collaborators. In this context, we propose an approach of collaboration recommendation that relies on community detection technique to find potential collaborators that can help in problem solving. Our contribution consists on proposing a combined metric that con...

École Normale Supérieure de Lyon

In this paper, an eecient algorithm to simultaneously implement array alignment and data/computation distribution is introduced and evaluated. We re-visit previous work of Li and Chen 13, 14], and we show that their alignment step should not be conducted without preserving the potential parallelism. In other words, the optimal alignment may well sequentialize computations, whatever the distribu...
