Researchers have introduced F$^2$STNet, a novel federated learning framework designed for graph-structured spatiotemporal forecasting. This model integrates spectral graph-Fourier features with a linear-complexity state-space temporal encoder and a graph convolution layer. To address data heterogeneity in decentralized environments, F$^2$STNet employs a Fairness-aware Federated Aggregation (FFA) mechanism that refines the standard FedAvg approach. Experiments on datasets like PeMS04, HZMetro, and KnowAir demonstrate improved forecasting accuracy and fairness in federated settings. AI
