In this paper we propose a novel feature selection method based on LSTSVM, termed as 1-Norm Least Squares Twin Support Vector Machines (NELSTSVM). A simple technique used in NELSTSVM is to apply a Tikhonov regularization term that is often used to regularize least squares . Then, we easily convert this formulation to a standard LP by replacing ...Cited by: 57

Least Squares Twin Support Vector Machine (LST-SVM) has been shown to be an efficient and fast algorithm for binary classification. In many real-world applications, samples may not deterministically be assigned to a single class; they come naturally with their associated uncertainties Also, samples may not be equally important and their importance degrees affect the classification.Author: Javad Salimi Sartakhti, Homayun Afrabandpey, Nasser Ghadiri
2.2 Least Squares Twin Support Vector Machine To further improve the computational speed of classifier, LS-TSVM  was pro-posed in the spirit of TSVM, and it seeks to solve a pair of smaller-sized QPPs rather than a single large-sized one as in LS-SVM. The illustration of the least squares TSVM is shown as Fig. 2. Fig. 2.

To overcome the above shortcoming, we propose l p norm least square twin support vector machine (l p LSTSVM). Our new model is an adaptive learning procedure with l p -norm (0< p <1), where p is viewed as an adjustable parameter and can be automatically chosen by data.
Least-squares support-vector machines (LS-SVM) are least-squares versions of support-vector machines (SVM), which are a set of related supervised learning methods that analyze data and recognize patterns, and which are used for classification and regression analysis.In this version one finds the solution by solving a set of linear equations instead of a convex quadratic programming (QP ...
Furthermore, the Newton method with fast convergence ability was used to solve the problem of external penalty in the linear programming dual problem. Thus, a 1-norm least squares twin support vector machine (NLSTWSVM) learning algorithm that can automatically select a sample feature was proposed.
