1. INTRODUCTION Feature selection (FS) methods have been used in the since 70s, using in the fields of statistics and pattern recognition. Pattern recognition system is one of the most important and indispensable tasks in overcome the curse of dimensionality problem, which forms a motivation for using a suitable feature selection method. According to their working principles, there are two types of methods are using in feature selection: methods which select the best subset of features that has a certain number of features And methods which select the best subset of features according to their own principles, independent of outside size measures [base]. Feature Selection (FS) is a process by using to select a most informative feature from the given medical data sets. It is used to improving predictive accuracy and reduces the computation cost for diagnosis of the disease. FS can be divided into two categories: supervised and unsupervised. Supervised feature selection is applied for data are available in the class label; otherwise unsupervised …show more content…

The support vector machine classifier creates a hyper plane or multiple hyper planes in high dimensional space that is useful for classification, regression and other efficient task. SVM have a many attractive features due to this gaining popularity and have promising empirical performance. SVM build hyper plane in original input space to separate the data points. Some time that is difficult to perform separation of data points in original input space, so to make separation easier the original finite dimensional space mapped into new higher dimensional space. SVM is works on principal that data points are classified using a hyper plane which maximizing the separation between data points and the hyper plane is constructed with the help of support vectors
