La présente note a pour objet de présenter un cadre formalisé de l'optimisation de la maintenance d'une voie, la maintenance en question comportant d'une part des opérations continues d'entretien courant et d'autre part, à intervalles espacés, des opérations de régénération de...

This report presents and proposes several methods to improve the capacity of generalization of the learning algorithms in a context of financial decision-making. These methods, overall, aim at controlling the capacity of the learning algorithms in order to limit the problem of the over-training,...

In a representative-agent model of intertemporal consumption-saving with stochastic income and habit formation, we have shown that precautionary savings observed in the data cannot be attributed only to income uncertainty, but also to the time-non-separability of preferences. We have found that,...
