Measuring the optimistic bias of cross-validation in radiomics
Abstract In radiomics, independent external data are often unavailable and cross-validation (CV) schemes are widely used to obtain performance estimates. Simple k-fold CV is preferred over nested CV due to its lower computational cost, although nested CV is known to provide more accurate estimates....
