New Support Vector Algorithms

TLDR
A new class of support vector algorithms for regression and classification that eliminates one of the other free parameters of the algorithm: the accuracy parameter in the regression case, and the regularization constant C in the classification case.
Abstract
We propose a new class of support vector algorithms for regression and classification. In these algorithms, a parameter ν lets one effectively control the number of support vectors. While this can be useful in its own right, the parameterization has the additional benefit of enabling us to eliminate one of the other free parameters of the algorithm: the accuracy parameter epsilon in the regression case, and the regularization constant C in the classification case. We describe the algorithms, give some theoretical results concerning the meaning and the choice of ν, and report experimental results.

Cross Validation Through Two-Dimensional Solution Surface for Cost-Sensitive SVM

TL;DR: Experimental results not only show that the proposed CV-SES has a better generalization ability than CS-SVM with various hybrids between grid search and solution path methods, and than recent proposed cost-sensitive hinge loss SVM with three-dimensional grid search, but also show that CV- SES uses less running time.

A heuristic weight-setting strategy and iteratively updating algorithm for weighted least-squares support vector regression

TL;DR: A heuristic weight-setting method is proposed, which derives from the idea of outlier mining, and is independent of unweighted LS-SVM, and a fast iterative updating algorithm is presented, which reaches the final results of WLS-S VM through a few updating steps instead of directly retraining WLS -SVM.
