pFedBBN: A Personalized Federated Test-Time Adaptation with Balanced Batch Normalization for Class-Imbalanced Data
PositiveArtificial Intelligence
- The introduction of pFedBBN, a personalized federated test-time adaptation framework, addresses the critical challenge of class imbalance in federated learning. This framework utilizes balanced batch normalization to enhance local client adaptation, particularly in scenarios with unseen data distributions and domain shifts.
- This development is significant as it provides a solution to the limitations of existing methods that require labeled data or client coordination, thereby improving the adaptability of federated learning systems in real-world applications.
- The ongoing challenges in federated learning, such as client heterogeneity and the need for personalized fine-tuning, highlight the importance of frameworks like pFedBBN. These innovations aim to balance global model performance with local data characteristics, addressing the persistent issues of data privacy and model robustness in decentralized environments.
