What is recorded here?
Preconditioned momentum gradients with moving averages of infrequently estimated Hessian diagonals and clipped coordinate updates, comparing two inexpensive curvature estimators.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
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.
