Analysis
This paper addresses the communication bottleneck in distributed learning, particularly Federated Learning (FL), focusing on the uplink transmission cost. It proposes two novel frameworks, CAFe and CAFe-S, that enable biased compression without client-side state, addressing privacy concerns and stateless client compatibility. The paper provides theoretical guarantees and convergence analysis, demonstrating superiority over existing compression schemes in FL scenarios. The core contribution lies in the innovative use of aggregate and server-guided feedback to improve compression efficiency and convergence.
