**WP1**: It will develop suitable dependence measures for non-continuous random vectors, also by using suitable metrics recently introduced in the space of subcopulas. Moreover, it will quantify the impact of the presence of ties in the statistical analysis of dependence models, also by means of new methodologies relying on the notion of entropy.

**WP2**: In collaboration with Napoli and Salerno units, it will study suitable copula models and/or association measures to describe the behavior of stochastic reliability systems with complex interactions (e.g. shared components). Moreover, it will study suitable functional inequalities (for copulas and distortion of copulas) able to describe ageing property of a system.

**WP6**: First it aims to construct effective cost-functions for the maximum entropy approach by taking into account results on single neuron inspections by other units (e.g. suitable modification of integrate&fire neurons more biologically tolerated). Then, we will test the emerging properties of small clusters of these "improved neurons" (a so called "neural network"), namely properties that are present at the network level but get lost when reducing back to single neurons. This quests for a heavily usage of consolidated techniques in the statistical mechanics of disordered systems as the stochastic stability analysis or the cavity field/belief-propagation routes.

Gianfausto Salvadori is Assistant Professor of Probability and Mathematical Statistics at the Department of Mathematics and Physics “Ennio De Giorgi” of the University of Salento. His research interests mainly lie in the multivariate statistical modelling of (extreme) environmental phenomena, both maritime, terrestrial and atmospheric. A particular attention is devoted to the assessment of the corresponding multivariate hazards, where the dependencies of the variables at play are modelled via Copulas. |
