FraQ: Efficient Coordinate-Space Recompression for Federated Low-Rank Adaptation

FraQ, an efficient coordinate-space recompression method for federated LoRA, is proposed, an efficient coordinate-space recompression method for federated LoRA that achieves accuracy close to uncompressed baselines while substantially reducing downlink communication with low server-side recompression overhead.
