Abstract:
Big data research has been receiving numerous attentions from industry and academia due to its vast application potential in business, manufacturing, health-care, and government agencies since over ten years ago when Google initiated the MapReduce project. Some new data-intensive and interesting research fields and problems have emerged. Class imbalance problems become the greatest issue in big data mining because of the unbounded size and imbalance nature of datasets. Under-sampling is a popular data preprocessing method in dealing with class imbalance problems with the purposes of balancing datasets to achieve a high classification rate and avoiding the bias toward majority samples. It always uses full minority data in a training dataset. However, some noisy minority examples may reduce the performance of classifiers. In this talk, a new under-sampling scheme is given by incorporating a noise filter before executing resampling. In order to verify the efficiency, this scheme is implemented based on four popular under-sampling methods. Experimental results indicate that the proposed scheme can improve the original undersampling-based methods with significance in terms of the popular metrics for imbalanced classification.
