FedSVD: Adaptive Orthogonalization for Private Federated Learning with LoRA

#1209 · Seanie Lee, Sangwoo Park, Dong Bok Lee, Dominik Wagner, Haebin Seong, Tobias Bocklet, Juho Lee, Sung Ju Hwang

FedSVD mitigates noise amplification in differentially private federated fine-tuning with LoRA by periodically refactorizing LoRA matrices via SVD, improving stability and performance under DP-SGD.
