What is recorded here?
Used Hessian-gradient products at initialization to score weight removals by their first-order effect on gradient norm, then trained the selected sparse subnetwork.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
This is a data-dependent pruning heuristic. Neural-tangent-kernel discussion motivates trainability but constant-kernel/infinite-width conditions do not prove finite-network accuracy or globally optimal masks. It differs from SNIP's immediate-loss sensitivity; all reported training comparisons remain benchmark-specific.

GraSP: pruning before training by gradient-signal preservation
