The Role of KL Divergence & Entropy
FedKLEntropy utilizes Kullback-Leibler (KL) divergence to measure the dissimilarity between client model weight distributions and the global model. By incorporating an entropy-based weighting mechanism, the algorithm robustly identifies and prioritizes clients whose local model updates are statistically closer to the global consensus, effectively mitigating client drift caused by non-i.i.d data heterogeneity without requiring sensitive server-side data or complex auxiliary losses.
