| | Classification for Imbalanced Data Using Feature Selection and Undersampling Methods | Friday 11:20 - 12:40 | |
| | Abstract:
In data mining and machine learning, the real-world data involve a large number of features, and frequently suffer from problem of class imbalance. However, in general, all of the features are not necessary since many of them can be redundant or even irrelevant, which may decrease the performance of an employed algorithm, e.g., a classification algorithm, and also traditional classifiers for a highly imbalanced dataset tend to bias in majority classes and, as a result, the minority class samples are usually misclassified as majority class. So, to overcome these problems, a proper feature selection approach that identifies informative feature subsets from large dimensional datasets, and an efficient sampling technique that removes some majority samples or creates new minority class samples can be used. The feature selection aims to reduce the dimensionality of the data and increase the performance of an algorithm by selecting only a small, but suitable subset of relevant features from the original large-scale dataset. So, various useful feature selection algorithms have been developed and applied to the problem of finding a suitable subset of features in multivariate datasets, often posed as single- or multi-objective optimization problems. And also, to cope with classification for imbalanced data, many machine learning approaches have been developed, most of which have been based on sampling techniques, cost sensitive learning, and ensemble methods. Particularly, some undersampling approaches have been utilized to eliminate the harms of skewed distribution by discarding the intrinsic samples in the majority class. Therefore, in this research, we propose an efficient, but simple cluster-based undersampling method for resolving class imbalance problem with a new feature selection method based on pairwise comparison, and then compare the performance of the classification model to those of others models with respect to various performance measures.
