Abstract: Methods and systems for federated learning with client clustering are described. A central server conducts rounds of intra-cluster training with two or more clusters to learn, for each cluster, a set of cluster parameters for a respective cluster model. The server merges two clusters into a new merged cluster by communicating, to each client of the two clusters, the cluster parameters of each of the two clusters. The server receives, from each client of the two clusters, performance indicators based on performance of each set of cluster parameters at each client. The central server determines, from the performance indicators, that one of the two clusters should be merged with the other cluster, and defines the new merged cluster to be a union of the two clusters. One set of cluster parameters is selected to be the cluster parameters for the new merged cluster.
