Abstract
A method for performing federated learning includes initializing, by a server, a global model G. The server shares Gwith a plurality of participants (N) using a secure communications channel. The server selects n out of N participants, according to filtering criteria, to contribute training for a round r. The server partitions the selected participants n into s groups and informs each participant about the other participants belonging to the same group. The server obtains aggregated group updates AU, . . . , AUfrom each group and compares the aggregated group updates and identifies suspicious aggregated group updates. The server combines the aggregated group updates by excluding the updates identified as suspicious, to obtain an aggregated update U. The server derives a new global model Gfrom the previous model Gand the aggregated update Uand shares Gwith the plurality of participants.
