Preconditioned momentum gradients with moving averages of infrequently estimated Hessian diagonals and clipped coordinate updates, comparing two inexpensive curvature estimators.
Scientific scope
Preconditioned momentum gradients with moving averages of infrequently estimated Hessian diagonals and clipped coordinate updates, comparing two inexpensive curvature estimators. Second-order estimates and clipping have additional costs; reported twofold gains concern125M–770M GPT2/OpenWebText settings. Source theoretical results have assumptions not certified here and do not establish global convergence or universal condition-number independence.
