Researchers have introduced CALM, a novel approach to decentralized federated learning that enhances model performance, particularly under non-independent and identically distributed (non-IID) data conditions. Unlike traditional methods that rely on parameter averaging and require identical client architectures, CALM employs decentralized federated distillation. This method allows clients to distill knowledge from peer model snapshots, eliminating the need for a central server or shared architecture. CALM further refines this by introducing a three-level trust gate: class-wise weighting based on agreement, sample-wise scaling based on teacher divergence, and a label gate to adjust distillation strength based on the true label's support. Tested on datasets like CIFAR-10 and SVHN with heterogeneous client architectures and Dirichlet label skew, CALM demonstrated superior performance compared to uniform and hard-filtered distillation methods.
