Researchers have developed a new regularization technique called HiFedProx for federated learning, which improves upon the existing FedProx method. HiFedProx replaces the quadratic penalty with a power-type regularizer indexed by p, allowing for better control over client parameter displacements. Experiments on a FEMNIST subset showed that HiFedProx achieved substantial gains under stress conditions, with optimal performance observed for p values between 5 and 7. AI
