Achieving Linear Speedup in Asynchronous Federated Learning with Heterogeneous Clients

no code implementations17 Feb 2024 Xiaolu Wang, Zijian Li, Shi Jin, Jun Zhang

Federated learning (FL) is an emerging distributed training paradigm that aims to learn a common global model without exchanging or transferring the data that are stored locally at different clients.

Distributionally Robust Graph Learning from Smooth Signals under Moment Uncertainty

no code implementations12 May 2021 Xiaolu Wang, Yuen-Man Pun, Anthony Man-Cho So

To address this issue, we propose a novel graph learning model based on the distributionally robust optimization methodology, which aims to identify a graph that not only provides a smooth representation of but is also robust against uncertainties in the observed signals.
