Researchers have developed a novel method for estimating client contributions in Federated Learning without requiring access to client data. This approach utilizes the spectral entropy of final-layer updates to measure the diversity of information contributed by each client. Two practical schemes, SpectralFed and SpectralFuse, were introduced, demonstrating a strong correlation with client accuracy across various benchmarks and non-IID conditions. AI
