A Prediction Interval for the Misclassification Rate
Abstract
The misclassification
rate of a classifier is a non-smooth functions of the classifier. The
estimated rate suffers from bias due to over-fitting and the
misclassification rate is a “minimized" quantity. For both of these
reasons the construction of measures of confidence such as estimates of
variance and confidence/prediction intervals are challenging. We
discuss this problem and propose a method based on the use of a smooth
upper bound combined with the bootstrap.
This upper bound utilizes the surrogate loss that is used in the
construction of the classifier.
