Svm with hinge loss
Splet27. feb. 2024 · 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 $σ$ tends to $0$. By replacing the Hinge … SpletThe linear SVM problem is the problem of finding a line (or plane, etc.) in space that separates points of one class from points of the other class by the widest possible margin. ...
