New FedReLa method tackles class imbalance in federated learning

Researchers have introduced FedReLa, a new method designed to address class imbalance and data heterogeneity in federated learning. This approach utilizes a feature-dependent label re-allocator to correct biased global decision boundaries without needing to know the overall class distribution. FedReLa is a modular and model-agnostic technique that can be integrated with existing algorithmic methods to enhance performance, particularly for minority classes, and has demonstrated superior results compared to previous state-of-the-art methods in experiments.
