Feature selection is an important data preprocessing technique and has been widely studied in data mining, machine learning and granular computing. In this paper, we introduced an effective feature selection method using the hybrid approaches, that is, use the mutual information to select the candidate feature set, then, obtain the super-reduct space from the candidate feature set by a wrapper ...

This paper proposes an efficient, Chi-Square-based, feature selection method for Arabic text classification. In Data Mining, feature selection is a preprocessing step that can improve the classification performance. Although few works have studied the effect of feature selection methods on Arabic text classification, limited number of methods was compared. Furthermore, different datasets were u...

The generation of predictive models is a frequent task in data mining with the objective of generating high precise and interpretable models. The data reduction is an interesting preprocessing approach that can allow us to obtain predictive models with these characteristics in large size data sets. In this contribution, we analyze the predictive model extraction based on rules using a training ...

Feature selection is a preprocessing phase to machine learning, which leads to increase the classification accuracy and reduce its complexity. However, the increase of data dimensionality poses a challenge to many existing feature selection methods. This paper formulates and validates a method for selecting optimal feature subset based on the analysis of the Pearson correlation coefficients. We...

Assessing whether a model is a good fit to the data is non trivial. The standard practice is to compare a few machine learning techniques to learn a model from data, and pick the one with the highest predictive performance. The winner is considered the best fitting model. But each model may involve different machine learning algorithms that carry their own set of parameters and constraints impo...
