Single-Round Clustered Federated Learning via Data Collaboration Analysis for Non-IID Data

Sota Sugawara, Yuji Kawamata, Akihiro Toyoda +2

Federated Learning (FL) enables distributed learning across multiple clients without sharing raw data. When statistical heterogeneity across clients is severe, Clustered Federated…
