A Novel One Sided Feature Selection Method for Imbalanced Text Classification

The imbalance data can be seen in various areas such as text classification, credit card fraud detection, risk management, web page classification, image classification, medical diagnosis/monitoring, and biological data analysis. The classification algorithms have more tendencies to the large class and might even deal with the minority class data as the outlier data. The text data is one of t...

Data Preprocessing for Liver Dataset Using SMOTE

-The class imbalanced problem occurs in various disciplines when one of target classes has a small number of instances compare to other classes. A classifier normally ignores or neglects to detect a minority class due to the small number of class instances. It poses a challenge to any classifier as it becomes hard to learn the minority class samples. Most of the oversampling methods may generat...

A Prediction for Classification of Highly Imbalanced Medical Dataset Using Databoost.IM with SVM

Recently, Class imbalance problems have growing interest because of their classification difficulty caused by the imbalanced class distributions. In particular, many ensemble learning and machine learning methods have been proposed for classification of imbalance problem. However, these methods producing poor predictive accuracy of classification for two-class imbalanced dataset. In this paper,...

A Novel Ensemble Method for Imbalanced Data Learning: Bagging of Extrapolation-SMOTE SVM

Class imbalance ubiquitously exists in real life, which has attracted much interest from various domains. Direct learning from imbalanced dataset may pose unsatisfying results overfocusing on the accuracy of identification and deriving a suboptimal model. Various methodologies have been developed in tackling this problem including sampling, cost-sensitive, and other hybrid ones. However, the sa...

Improving SMOTE with Fuzzy Rough Prototype Selection to Detect Noise in Imbalanced Classification Data

In this paper, we present a prototype selection technique for imbalanced data, Fuzzy Rough Imbalanced Prototype Selection (FRIPS), to improve the quality of the artificial instances generated by the Synthetic Minority Over-sampling TEchnique (SMOTE). Using fuzzy rough set theory, the noise level of each instance is measured, and instances for which the noise level exceeds a certain threshold le...
