JPmHC Dynamical Isometry via Orthogonal Hyper-Connections

Researchers propose JPmHC (Jacobian-spectrum Preserving manifold-constrained Hyper-Connections), a new deep learning framework that improves upon existing Hyper-Connections by replacing identity skips with trainable linear mixers while controlling gradient conditioning. The framework addresses training instability and memory overhead issues in current deep learning architectures through constrained optimization on specific mathematical manifolds.
