Fine-Tuning Impairs the Balancedness of Foundation Models in Long-tailed Personalized Federated Learning

Shihao Hou, Chikai Shang, Zhiheng Yang +5

Personalized federated learning (PFL) with foundation models has emerged as a promising paradigm enabling clients to adapt to heterogeneous data distributions. However, real-world…

CUE: Concept-Aware Multi-Label Expansion to Mitigate Concept Confusion in Long-Tailed Learning

Ruichi Zhang, Chikai Shang, Jiacheng Yang +4

Long-tailed distributions are common in real-world recognition tasks, where a few head classes have many samples while most tail classes have very few. Recently, fine-tuning founda…
