Due to the non-smoothness of the Hinge loss in SVM, it is difficult to obtain a faster convergence rate with modern optimization algorithms. In this paper, we introduce two smooth Hinge losses ψ_G (α;σ) and ψ_M (α;σ) which are infinitely differentiable and converge to the Hinge loss uniformly in α as σ ...
