Personalized Federated Learning for Spatio-Temporal Forecasting: A Dual Semantic Alignment-Based Contrastive Approach

no code implementations4 Apr 2024 Qingxiang Liu, Sheng Sun, Yuxuan Liang, Jingjing Xue, Min Liu

From spatial perspective, we design lightweight-but-efficient prototypes as client-level semantic representations, based on which the server evaluates spatial similarity and yields client-customized global prototypes for the supplemented inter-client contrastive task.

Online Spatio-Temporal Correlation-Based Federated Learning for Traffic Flow Forecasting

no code implementations17 Feb 2023 Qingxiang Liu, Sheng Sun, Min Liu, Yuwei Wang, Bo Gao

In this paper, we perform the first study of forecasting traffic flow adopting Online Learning (OL) manner in FL framework and then propose a novel prediction method named Online Spatio-Temporal Correlation-based Federated Learning (FedOSTC), aiming to guarantee performance gains regardless of traffic fluctuation.

Exploring the Distributed Knowledge Congruence in Proxy-data-free Federated Distillation

2 code implementations14 Apr 2022 Zhiyuan Wu, Sheng Sun, Yuwei Wang, Min Liu, Quyang Pan, Junbo Zhang, Zeju Li, Qingxiang Liu

Federated distillation (FD) is proposed to simultaneously address the above two problems, which exchanges knowledge between the server and clients, supporting heterogeneous local models while significantly reducing communication overhead.
