Mercredi 8 janvier, nous aurons le plaisir d’écouter Joon Kwon (INRAE). La séance aura lieu à 14h dans la salle Paul Erdös (A115), au centre Inria de Paris.
A regret minimization approach to fixed point iterations
Résumé : We present a link between regret bounds and fixed point problems with nonexpansive maps. This allows the definition of many new fixed point iterations based on regret minimizing algorithms with corresponding convergence guarantees. In particular, we transpose the celebrated AdaGrad algorithm to obtain a fixed point iteration with strong adaptive properties.
