Contribution grade

Reference score155,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Uses implicit Hessian-vector products and inverse-Hessian approximations to estimate how training-point reweighting or perturbations affect model predictions, with selected data-debugging experiments.

Scientific scope

Uses implicit Hessian-vector products and inverse-Hessian approximations to estimate how training-point reweighting or perturbations affect model predictions, with selected data-debugging experiments. Inherits influence functions from robust statistics and second-order optimization. Formal local derivation needs differentiability and positive-definite Hessian; nonconvex/nonsmooth applications use approximations, not exact leave-one-out retraining. No universal reliability claim.

Evidence

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
