Classification with Support Vector Machines

Classification is very common task in chemometrics and several methods are reported in the literature for solving this type of problems. The choice of the most appropriate method depends on the specific nature of the problem, for example how many classes, objects and variables describe the dataset and so on. In simpler cases (e.g. linear boundaries, many samples and fewer variables) many algorithms may perform satisfactorily, whereas for most complicated cases the choice for reaching optimal performance is usually more restricted.
Support Vector Machines (SVMs) are a further approach for classification that has been introduced only recently by researchers from the machine learning community. They have attracted much attention due to some particular features amongst which their flexibility to deal with tasks of diverse complexity, their robustness and computational efficiency when dealing with many variables and their clear connection to statistical learning theory. In this article we introduce the main features of SVMs by means of simple numerical examples.
