Graphical representation of threefold cross-validation: (a) dataset is partitioned into K = 3 disjoint subsets \(\{{\mathrm{D}}_{1},{\mathrm{D}}_{2},{\mathrm{D}}_{3}\}\), and (b) K = 3 training trials. In each trial, one of \({\mathrm{D}}_{1},{\mathrm{D}}_{2}\mathrm{ or }{\mathrm{D}}_{3}\) is used as the test set.
