What is Expected Prediction Error (EPE) a function of?

WebThe authors adopted a sampling approach to estimate the expected reduction in error due to the labeling of a query, and the future error rate was estimated by log-loss using the entropy of the posterior class distribution on a sample of the unlabeled examples. WebThis paper takes a sampling approach to error estimation and the choice of query. Rather than estimating expected error over the full distribution, , we measure it over the sample … reces noord holland https://unrefinedsolutions.com
