Optimization and dynamical processes in statistical learning and inverse problems

September, 8-12, 2014 | Fondazione Mediaterraneo, Sestri Levante (GE), Italia

The purpose of the workshop is to stimulate discussions and possible collaborations between italian and french researchers on the following topics: algorithms on convex optimization and monotone inclusions, fixed-point methods, game theory, interplay between discrete and continuous dynamics, statistical learning theory, big data processing, inverse problems.
