Communication-Efficient Agnostic Federated Learning via Faster Convergence and Compression
Haomin Bai, Junyan Sun, Sifan Yang +2
Agnostic federated learning (AFL) seeks a model that performs reliably across heterogeneous workers, but communication remains a bottleneck. We improve communication efficiency…
