In text classification, feature selection is essential to improve the classification effectiveness. This paper provides an empirical study of a feature selection method based on genetic algorithms for different text representation methods. This feature selection algorithm can accomplish two goals: in one hand is the search of a feature subset such that the performance of classifier is best; in other...
Intrusion Detection Systems (IDS) play an important role in identifying possible attacks to the networks. Most algorithms create a model; and the classification is done based on that model. During the classification, one of the main concerns is increasing the accuracy and the reliability. Traditional intrusion detection methods have some problems such as high false alarm rate, low detection compatibility...
In this paper, multidimensional and time-varying haptic-based handwritten signatures are analyzed within a visual data mining paradigm while relying on unsupervised construction of virtual reality spaces using classical optimization and genetic programming. Specifically, the suggested approaches make use of nonlinear transformations to map a high dimensional feature space into another space of smaller...
Software cost estimation affects almost all activities of software project development such as: bidding, planning, and budgeting, thus it is very crucial to the success of software project management. In past decades, many methods have been proposed for cost estimation. Analogy based cost estimation (ABE) is among the most popular techniques due to its conceptual simplicity and empirical competitiveness...
