Correlation-based Feature Ranking in Combination with Embedded Feature Selection
Original language description
Most of Feature Ranking and Feature Selection approaches can be used for categorial data only. In this paper we present new methods for feature ranking and selection obtained as a combination of the above mentioned approaches. The data mining algorithm (GAME) is designed for numerical data, but it can be applied to categorial data as well. It incorporates feature selection mechanisms and new methods, proposed in this paper, derive feature ranking from final data mining model. The rank of each feature selected by model is computed by processing correlations of outputs between neighboring model's neurons in different ways. We used four different methods based on fuzzy logic, certainty factors and simple calculus. The performance of these four feature ranking methods was tested on artificial data sets and on well known real world data sets. These methods produce ranking consistent with recently published studies.
