A Novel Class Imbalance Learning Method using Neural Networks

چکیده
In Data mining and Knowledge Discovery hidden and valuable knowledge from the data sources is discovered. The traditional algorithms used for knowledge discovery are bottle necked due to wide range of data sources availability. Class imbalance is a one of the problem arises due to data source which provide unequal class i.e. examples of one class in a training data set vastly outnumber examples of the other class(es). In this paper, we present a new hybrid approach using neural networks to improve the class imbalance results. This algorithm provides a simpler and faster alternative by using multi perceptron back propagation neural network as base algorithm. We conduct experiments using eleven UCI data sets from various application domains using four base learners, and five evaluation metrics. Experimental results show that our method has shown good performance in terms of Area under the ROC Curve, F-measure, precision, TP rate and TN rate values than many existing class imbalance learning methods.

متن کاملA hybrid method to face class overlap and class imbalance on neural networks and multi-class scenarios
Class imbalance and class overlap are two of the major problems in data mining and machine learning. Several studies have shown that these data complexities may affect the performance or behavior of artificial neural networks. Strategies proposed to face with both challenges have been separately applied. In this paper, we introduce a hybrid method for handling both class imbalance and class ove...
متن کاملDiscriminative Sparse Neighbor Approximation for Imbalanced Learning
Data imbalance is common in many vision tasks where one or more classes are rare. Without addressing this issue, conventional methods tend to be biased toward the majority class with poor predictive accuracy for the minority class. These methods further deteriorate on small, imbalanced data that have a large degree of class overlap. In this paper, we propose a novel discriminative sparse neighb...

In this paper, face detection problem is considered using the concepts of compressive sensing technique. This technique includes dictionary learning procedure and sparse coding method to represent the structural content of input images. In the proposed method, dictionaries are learned in such a way that the trained models have the least degree of coherence to each other. The novelty of the prop...
