Data Shapley: learner-dependent data valuation and practical estimators

Contribution grade

AI interpretability, model editing and data attribution · Human-designed research method or resource

Reference score135,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Applies cooperative-game marginal contribution valuation to training data for a fixed learner and utility, with Monte Carlo, truncation and gradient-based approximation strategies.

Scientific scope

Applies cooperative-game marginal contribution valuation to training data for a fixed learner and utility, with Monte Carlo, truncation and gradient-based approximation strategies. Inherits the Shapley uniqueness result rather than inventing it; values depend on dataset, learner and utility, not universal monetary value. Exact computation is exponential; truncation and gradient shortcuts are not exact unbiased Shapley values. Only general ML/image/synthetic scope is curated, excluding biomedical applications.

Evidence

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