Reference score115,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Computes a ratio of distances to the predicted and nearest alternative class high-density sets, providing a model-agnostic confidence ranking with conditional density-estimation analysis.

Scientific scope

Computes a ratio of distances to the predicted and nearest alternative class high-density sets, providing a model-agnostic confidence ranking with conditional density-estimation analysis. Bayes-agreement guarantees require compact-support/density-level-set, manifold/noise and class-margin conditions; agreement with the Bayes classifier is not certainty of correctness. Large-scale experiments skip filtering/use PCA, so theory and heuristic differ.

Evidence

The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof. Bayes-agreement guarantees require compact-support/density-level-set, manifold/noise and class-margin conditions; agreement with the Bayes classifier is not certainty of correctness.
