1. A computer-implemented method, comprising: obtaining first weight information indicating a first set of delta values, the first set of delta values including a first delta value for each weight in a set of weights, the set of weights including a weight for each of a set of one or more parameters of a model; obtaining second weight information indicating a second set of delta values, the second set of delta values including a second delta value for each weight in the set of weights; and generating combined weight information including a combined set of delta values or a combined set of weights based, at least in part, upon the first weight information and the second weight information.
