NVFlare provides FedAvg and several approaches for federated learning under heterogeneous/non-IID data, including FedProx and SCAFFOLD. However, FedAvg aggregation is primarily driven by client sample size, which may not adequately represent the information value of individual clients when their local data distributions differ significantly. A large client whose distribution is highly redundant with other participants can dominate aggregation, while a smaller client containing underrepresented patterns may have limited influence on the resulting global model. It would be useful to support an optional heterogeneity-aware dynamic weighting strategy for FedAvg. Instead of determining aggregation coefficients only from the number of local samples, the strategy could combine sub-linear sample-size weighting with a configurable heterogeneity or representation score. For example, a client-side distribution descriptor could be compared with an aggregated reference distribution using a measure
