Optimal Design of Radial Basis Function for Intrusion Detection Data

Authors : M. Govindarajan and R.M. Chandrasekaran

Abstract: Data Mining is the use of algorithms to extract the information and patterns derived by the knowledge discovery in databases process. Classification maps data into predefined groups or classes. It is often referred to as supervised learning because the classes are determined before examining the data. In many data mining applications that address classification problems, feature and model selection are considered as key tasks. That is, appropriate input features of the classifier must be selected from a given set of possible features and structure parameters of the classifier must be adapted with respect to these features and a given data set. This study describes an Evolutionary Algorithm (EA) that performs feature selection and model selection simultaneously for Radial Basis Function (RBF) classifiers. In order to reduce the optimization effort, various techniques are integrated that accelerate and improve the EA significantly: hybrid training of RBF networks, comparative cross validation. The feasibility and the benefits of the proposed approach are demonstrated by means of data mining problem: intrusion detection in computer networks. It is shown that, compared to earlier RBF technique, the run time is reduced by up to 0.13 and 0.06% while, error rates are lowered by up to 0.01 and 0.01% for normal and abnormal behavior, respectively. The algorithm is independent of specific applications so that many ideas and solutions can be transferred to other classifier paradigms.
