Claim 7:
8. One or more computer-readable storage media collectively containing computer program code that, when executed by operation of one or more computer processors, performs an operation comprising:
issuing one or more queries to a plurality of participants in a federated learning system;
receiving a first set of replies from the plurality of participants;
generating a first aggregated model based on the first set of relies, a first influence vector, and an initial model; and
upon determining that a predefined criterion is satisfied, during a first epoch:
generating a second influence vector modifying a weight of a first participant of the plurality of participants,
generating a second aggregated model based on the first set of replies, the second influence vector, and the initial model,
generating a third influence vector modifying a weight of a first participant of the plurality of participants, and
generating a third aggregated model based on the first set of replies, the third influence vector, and an initial model; and

upon determining that a number of aggregated models in a set of aggregated models, including the first, second and third aggregated models, exceeds a predefined maximum value, pruning one or more of the first, second or third aggregated models during a second epoch based on model performance.
