چکیده
Imbalanced class distribution affects many applications in machine learning, including medical diagnostics, text classification, intrusion detection and others. In this paper, we propose a novel ensemble classification method designed to deal with imbalanced data. The proposed trains each tree the using uniquely generated synthetically balanced data balancing is carried out via kernel density estimation, which offers natural effective approach generating new sample points. We show that results lower variance of model estimator. tested against benchmark classifiers on range simulated real-life experiments classifier significantly outperforms methods.

Online Ensemble Learning for Imbalanced Data Streams
While both cost-sensitive learning and online learning have been studied extensively, the effort in simultaneously dealing with these two issues is limited. Aiming at this challenge task, a novel learning framework is proposed in this paper. The key idea is based on the fusion of online ensemble algorithms and the state of the art batch mode cost-sensitive bagging/boosting algorithms. Within th...
متن کاملCompact Ensemble Trees for Imbalanced Data
This paper introduces a novel splitting criterion parametrized by a scalar ‘α’ to build a class-imbalance resistant ensemble of decision trees. The proposed splitting criterion generalizes information gain in C4.5, and its extended form encompasses Gini(CART) and DKM splitting criteria as well. Each decision tree in the ensemble is based on a different splitting criterion enforced by a distinct...
متن کاملEnsemble-based hybrid probabilistic sampling for imbalanced data learning in lung nodule CAD
Classification plays a critical role in false positive reduction (FPR) in lung nodule computer aided detection (CAD). The difficulty of FPR lies in the variation of the appearances of the nodules, and the imbalance distribution between the nodule and non-nodule class. Moreover, the presence of inherent complex structures in data distribution, such as within-class imbalance and high-dimensionali...
متن کاملDynamic Cost-sensitive Ensemble Classification based on Extreme Learning Machine for Mining Imbalanced Massive Data Streams
In order to lower the classification cost and improve the performance of the classifier, this paper proposes the approach of the dynamic cost-sensitive ensemble classification based on extreme learning machine for imbalanced massive data streams (DCECIMDS). Firstly, this paper gives the method of concept drifts detection by extracting the attributive characters of imbalanced massive data stream...
متن کاملLearning from Imbalanced Data Using Ensemble Methods and Cluster-Based Undersampling
Imbalanced data, where the number of instances of one class is much higher than the others, are frequent in many domains such as fraud detection, telecommunications management, oil spill detection and text classification. Traditional classifiers do not perform well when considering data that are susceptible to both within-class and between-class imbalances. In this paper, we propose the ClustFi...
