This paper identifies a geometric mismatch in the Dion low-rank spectral optimizer and proposes Orth-Dion, which replaces column normalization with QR orthogonalization to close the convergence gap to full-rank methods like Muon at the same communication cost, validated on large-scale language model pre-training.
EdgeDetect is a federated intrusion detection system for 6G-IoT environments that combines importance-aware gradient binarization (32× compression) with Paillier homomorphic encryption to achieve 98% accuracy on CIC-IDS2017 while reducing communication overhead by 96.9% and enabling deployment on resource-constrained devices like Raspberry Pi 4.
