    Appl Math: Diego Klabjan on "Federated Low-rank Learning"

    Title: Federated Low-rank Learning

    Speaker: Diego Klabjan, Northwestern University

    Abstract:

    Federated Learning (FL) faces significant challenges related to communication efficiency and performance reduction when scaling to many clients. To address these issues, we explore the potential of using low-rank updates and provide the first theoretical study of rank properties in FL. Our theoretical analysis shows that a client’s loss exhibits a higher-rank structure (i.e., gradients span higher-rank subspaces of the Hessian) compared to the server’s loss, and that low-rank approximations of the clients’ gradients have greater similarity. Consequently, we propose FedLoRU, a general low-rank update framework for FL. Our framework enforces low-rank client-side updates and accumulates these updates to form a higher rank model. Experimental results demonstrate that FedLoRU performs comparably to full-rank algorithms and exhibits robustness.
