Default Re: Ecv versus Eout versus Etest

The digits problem is about classification, so all errors are classification errors.

However, one can us different algorithms to get your final classifier, one being the regression algorithm treating the y_n=\pm 1 as real values not binary classification values. The algorithm you use to get your final classifier is up to you, but the final result has to be a classifier.
