Research Paper Overview
Beyond Rebalancing: Benchmarking Binary Classifiers Under Class Imbalance Without Rebalancing Techniques
Summary
This study evaluates binary classifiers' performance under class imbalance without using rebalancing methods. It benchmarks diverse classifiers on real and synthetic datasets with varying minority class sizes and data complexities. Results show that while traditional classifiers degrade under extreme imbalance, advanced models like TabPFN and boosting ensembles maintain better performance and generalization. The work guides model selection for imbalanced learning without explicit rebalancing.
