Online confidence interval estimation for federated heterogeneous optimization .

Figures of the Article

Impacts of $\tau$ based on $1000$ replications. The $x$ -axis and $y$ -axis are the number of rounds and $\left \| \bar{ {\theta}}_T- {\theta}^* \right \|$ , respectively. “Balance” means identical number of local iterations, where $E_i=4$ for all $i\in[N]$ and $\tau=160$ . “Small” means a small degree of heterogeneity in the number of local iterations, where $E_i$ is IID from a discrete uniform distribution on $\{3, 4, 5\}$ , and $\mathbb{E}\tau=500/3$ . “Large” represents a large degree of heterogeneity in the number of local iterations, where $E_i$ is IID from a discrete uniform distribution on $\{1, 2, 3, 4, 5, 6, 7\}$ , and $\mathbb{E}\tau=200$ .
