The support vector machine (SVM) is a supervised learning method that generates input-output mapping functions from a set of labeled training data. But you can also play with SVM if you are a C# afficionados. , it creates a “decision-maker” system which tries to predict new values. The algorithm was invented by Vladimir Vapnik and the current standard Support Vectors are simply the co-ordinates of individual observation. Support vector machines, or SVMs, is a machine learning algorithm for classification. Introduction The purpose of this paper is to provide an introductory yet extensive tutorial on the basic ideas behind Support Vector Machines (SVMs). We can have multiple class SVMs using One-Versus-One Classification or One-Versus-All Classification. SVR) - regression depends only on support vectors from the training data.
