Classifying imbalanced data sets using similarity based hierarchical decomposition
作者:
Highlights:
• A novel method for imbalanced dataset classification.
• A new hierarchical classifier which does not use a fixed feature/class hierarchy.
• Uses clustering and outlier detection to construct the hierarchy.
• Shows that different feature spaces can be used to build a hierarchy.
• Successful when the class imbalanced ratio is low, classes are highly overlapping.
