Fuzzy least squares support vector machines for multiclass problems

In least squares support vector machines (LS-SVMs), the optimal separating hyperplane is obtained by solving a set of linear equations instead of solving a quadratic programming problem. But since SVMs and LS-SVMs are formulated for two-class problems, unclassifiable regions exist when they are extended to multiclass problems. In this paper, we discuss fuzzy LS-SVMs that resolve unclassifiable ...

Fuzzy support vector machines for multiclass problems

Since support vector machines for pattern classification are based on two-class classification problems, unclassifiable regions exist when extended to n (> 2)-class problems. In our previous work, to solve this problem, we developed fuzzy support vector machines for oneto-(n−1) classification. In this paper, we extend our method to pairwise classification. Namely, using the decision functions o...

Fuzzy Least Squares Twin Support Vector Machines

Least Squares Twin Support Vector Machine (LSTSVM) is an extremely efficient and fast version of SVM algorithm for binary classification. LSTSVM combines the idea of Least Squares SVM and Twin SVM in which two nonparallel hyperplanes are found by solving two systems of linear equations. Although, the algorithm is very fast and efficient in many classification tasks, it is unable to cope with tw...

Fuzzy Pairwise Multiclass Support Vector Machines

At first, support vector machines (SVMs) were applied to solve binary classification problems. They can also be extended to solve multicategory problems by the combination of binary SVM classifiers. In this paper, we propose a new fuzzy model that includes the advantages of several previously published methods solving their drawbacks. For each datum, a class is rejected using information provid...

Least Squares Support Vector Machines: an Overview

Support Vector Machines is a powerful methodology for solving problems in nonlinear classification, function estimation and density estimation which has also led recently to many new developments in kernel based learning in general. In these methods one solves convex optimization problems, typically quadratic programs. We focus on Least Squares Support Vector Machines which are reformulations t...
