What are Capra-Convex Sets?
Jean-Philippe Chancelier, Michel de Lara, Adrien Le Franc +1
This paper focuses on a specific form of abstract convexity known as Capra-convexity, where a constant along primal rays (Capra) coupling replaces the scalar product used in standa…

Learning with Fitzpatrick Losses
Seta Rakotomandimby, Jean-Philippe Chancelier, Michel de Lara +1
Fenchel-Young losses are a family of convex loss functions, encompassing the squared, logistic and sparsemax losses, among others. Each Fenchel-Young loss is implicitly associated…
