In its simplest, linear form, an SVM is a hyperplane that separates a set of positive examples from a set of negative examples with maximum margin (see figure 1).

The Support Vector Machine (SVM) was first proposed by Vapnik and has since attracted a high degree of interest in the machine learning research community [2]. Several recent studies have reported that the SVM (support vector machines) generally are capable of delivering higher performance in terms of classification accurac Research has concentrated on developping and improving machine learning methods for such tasks. Some of the most widely used are maximum entropy, C4.5 and support vector machines. When attempting to tackle a natural language task, researchers experiment with various machine learning methods and a certain annotated dataset that the methods are.

Vapnik & Chervonenkis originally invented support vector machine. At that time, the algorithm was in early stages. Drawing hyperplanes only for linear classifier was possible. Later in 1992 Vapnik, Boser & Guyon suggested a way for building a non-linear classifier. They suggested using kernel trick in SVM latest paper This paper introduces Transductive Support Vector Machines (TSVMs) for text classi cation. While regular Support Vector Machines (SVMs) try to induce a general decision function for a learning task, Transductive Support Vector Machines take into account a particular test set and try to minimize misclassi cations of just those particular examples. The paper presents an analysis of why TSVMs are. 2.2 Support Vector Machines The aim of Support Vector Machines in the binary classification problem is to find the optimal separating hyperplane (this is the hyperplane that maximizes the geometric margin) in a high dimensional feature space X0.
