Researchers introduce DAMEL (Dual-Axis Multi-Expert Learning), a machine learning algorithm designed to address class-imbalanced datasets by simultaneously reducing prediction bias and variance. The method uses multiple expert models along representation and time axes, combining their strengths through concatenated representations and weight aggregation across training epochs.
Researchers introduce Rel-MOSS, a novel graph neural network approach designed to address class imbalance problems in relational database entity classification. The method uses relation-centric gating and minority oversampling techniques to prevent underrepresentation of minority classes, achieving 2-4% performance improvements over existing relational deep learning methods.
Researchers applied SMOTE-Tomek preprocessing to address class imbalance in requirements engineering classification, achieving 76.16% accuracy with logistic regression compared to a 58.31% baseline. The technique combines synthetic minority oversampling with Tomek link removal and stratified K-fold validation on the PROMISE dataset of 969 categorized requirements.
Researchers propose FEAT, a federated learning method that improves continual learning by addressing class imbalance and representation collapse across distributed clients. The approach combines geometric alignment and energy-based correction to better utilize exemplar samples while maintaining performance under dynamic heterogeneity.
Researchers propose Class-Aware Spectral Distribution Matching (CSDM), a new dataset distillation method that addresses performance issues on imbalanced datasets. The technique achieves 14% improvement over existing methods on CIFAR-10-LT with enhanced stability on long-tailed data distributions.
