Researchers have introduced Orthogonal Hyper-Connections (oHC) as a novel architecture for Transformer models, aiming to improve training stability and performance. Unlike previous Hyper-Connections (HC) that used unconstrained matrices, or manifold-constrained Hyper-Connections (mHC) that capped scaling factors, oHC restricts the mixing matrix to the rotation group SO(n). This approach prevents amplification or attenuation of residual streams, ensuring stable training and preserving stream diversity. The proposed method utilizes a pair of unit quaternions for parameterization, offering faster computation and outperforming baseline models on various downstream tasks. AI
