New Study Benchmarks Binary Classifiers Under Class Imbalance

A new study published on arXiv explores the performance of binary classifiers when faced with imbalanced datasets, focusing on scenarios without rebalancing techniques. Researchers evaluated various classifiers, including traditional models and advanced ones like TabPFN and boosting ensembles, across real-world and synthetic datasets with progressively smaller minority class sizes. The findings indicate that classification difficulty increases with data complexity and reduced minority class representation, but advanced models demonstrate superior robustness and generalization compared to traditional methods.
