Researchers have conducted a large-dimensional analysis of Generalized Total Variation Minimization (GTVMin) applied to least-squares models in federated learning. Using random matrix theory, they demonstrated that Lipschitz observations of the global GTVMin solution converge universally across different network structures in high dimensions. The study also provides precise analytical expressions for performance under both independent and identically distributed (i.i.d.) and non-i.i.d. Gaussian mixture distributions on fixed networks, quantifying the trade-off between local adaptation and collaboration through regularization. These theoretical findings were validated through experiments using synthetic and real-world data. AI
