Abstract:
In recent years many applications of data mining deal with a high-dimensional data (very large number of features) impose a high computational cost as well as the risk of “over fitting”. In these cases, it is common practice to adopt feature selection method to improve the generalization accuracy. Feature selection method has become the focus of research in the area of data mining where there exists a high-dimensional data. We propose in this paper a novel feature selection method based on two stage analysis of Fisher Ratio and Mutual Information. The two-stage analysis of Fisher Ratio and Mutual Information is carried out in the feature domain to reject the noisy feature indexes and select the most informative combination from the remaining. In the approach, we develop two practical solutions, avoiding the difficulties of using high dimensional Mutual Information in the application, that are the feature indexes clustering using cross Mutual Information and the latter estimation based on conditional empirical PDF. The effectiveness of the proposed method is evaluated by the SVM classifier using datasets from the UCI Machine Learning Repository. Experimental results show that the proposed method is superior to some other classical feature selection methods and can get higher prediction accuracy with small number of features. The results are highly promising.
