arXiv:2606.26037v1 Announce Type: cross Abstract: Federated learning has emerged as the foremost approach for decentralized model training with privacy preservation. The global class imbalance and cross-client data heterogeneity naturally coexist, and the mismatch between local and global imbalances exacerbates the performance degradation of the aggregated model. The agnosticism of global class distribution poses significant challenges for data-level methods, especially under extreme conditions with severe class absence across clients. In this paper, we propose FedReLa, a novel data-level appr
The increasing focus on privacy-preserving decentralized AI models necessitates solutions for practical challenges like data heterogeneity and imbalance in federated learning.
Improving federated learning's robustness to imbalanced data expands its applicability across diverse, real-world datasets, crucial for sensitive applications and distributed intelligence.
This research suggests a new method that could significantly enhance the performance and reliability of federated learning systems, especially under challenging data conditions.
