Alleviating Classification Problem of Imbalanced Dataset
The Class Imbalance problem occurs when there are many more instances of some class than others. i.e. skewed class distribution. In cases like this, standard classifier tends to be overwhelmed by the majority class and ignores the minority class. It is one of the 10 challenging problems of data mining research and pattern recognition. This imbalanced dataset degrades the performance of the clas...
متن کاملImbalanced Dataset Classification and Solutions: a Review
-Imbalanced data set problem occurs in classification, where the number of instances of one class is much lower than the instances of the other classes. The main challenge in imbalance problem is that the small classes are often more useful, but standard classifiers tend to be weighed down by the huge classes and ignore the tiny ones. In machine learning the imbalanced datasets has become a cri...
متن کاملCustomer Credit Scoring Method Based on the SVDD Classification Model with Imbalanced Dataset
Customer credit scoring is a typical class of pattern classification problem with imbalanced dataset. A new customer credit scoring method based on the support vector domain description (SVDD) classification model was proposed in this paper. Main techniques of customer credit scoring were reviewed. The SVDD model with imbalanced dataset was analyzed and the predication method of customer credit...
متن کاملWeighted Neighborhood Classifier for the Classification of Imbalanced Tumor Dataset
Machine learning is widely applied to gene expression pro ̄les based molecular tumor classi ̄cation, but sample imbalance problem is often overlooked. This paper proposed a subclassweighted neighborhood classi ̄er to address the imbalanced sample set problem and a novel neighborhood rough set model to select informative genes for classi ̄cation performance improvement. Experiments on three publicly...
متن کاملOn Mining Fuzzy Classification Rules for Imbalanced Data
Fuzzy rule-based classification system (FRBCS) is a popular machine learning technique for classification purposes. One of the major issues when applying it on imbalanced data sets is its biased to the majority class, such that, it performs poorly in respect to the minority class. However many cases the minority classes are more important than the majority ones. In this paper, we have extended ...
